I love GML, I really do. It's the first programming language I learned, and my journey with it started over 15 years ago with GameMaker 5. Over time, the language has received many updates and improvements, but there are still a number of oddities, inconsistencies, and omissions. In recent years, I've found myself filling the gaps with custom functions which are shared by a great many of my projects and assets. A few were published individually, but I decided it would be most helpful for myself and everyone else if I compiled a single package for them all.
Say hello to GML+!
GML+ is available now!

I took the MPE months ago. I’m wondering if my score on my MPE is good.
I've been trying to solve this on my own, but I've reached a point where the more info I absorb, the more confused and aimless my attempts become.
I'll explain what I'm trying to do with the attached image.
This is the basic setup. Three points (represented by sprites within a Node2D, the only nodes involved here), (a) and (b) are dynamic (more on this later), (c) is fixed and cannot move at all.
The points are positioned (and should ultimately move) in such a way that if I were to draw a triangle/two triangles as shown, the highlighted angle would always be exactly 90°. On top of this, the three sides of the highlighted triangle should also have a fixed *total* length.
With this in mind, (b) should move towards the midpoint between (a) and (c) as (a) moves further away (and vice versa), so as to preserve both the 90° angle and the total sum of all side lengths.
I feel like there must be a simple method to do exactly this, I'm just finding myself... keep reading on reddit ➡
That’s because I don’t understand sine language
I passed geometry (10th grade) with an average of a high D. Is trigonometry that harder. Do I have to worry? I'm scared.
If the sine is positive in the first quadrant, then why when I type sine (42) on the calculator does it show me a negative number?
Hi everyone, so does anyone knows how to solve this cosine equation?
cos(2t)-cos(t) = -0.5, 0 <= t <= 2pi
Solve this and round up to 3 decimal places

TL; DR: Just read the below first paragraph in bold and tell me if my assumption is correct or not (and why not, if that's the case, please)
My assumption is that any two great circles in a sphere intersect one to the other always at two unique points . Those two points are antipodal and divide each great circle in two equal halves.
Starting from that assumption, If I can trace the perpendicular distance from the "Midpoint" between the antipodals of one great circle (one of the two arcpoints at 90° of the antipodals) to the plane of the other great circle, and I also know the radius of the sphere, using arcsin [perpendicular distance from midpoint great circle one to plane of great circle two/ radius sphere] I can obtain the angle of relative inclination (obliquity) of the two great circles about the pivotal line that connect the two antipodals.
Knowing the obliquity then It's quite straigh... keep reading on reddit ➡
I created a 24 minute video that:
There are only 4 trig problems on the ACT Math section and it is my belief that with some practice, you can absolutely master the trig problems.
Enjoy the video - I hope it’s helpful!
Hi, I would like to go back to the basics by studying algebra and trigonometry all over again. But I don't want to study everything, I just want to master the important topics in algebra and trigo that I can use for Differential Calculus, Integral Calculus, Differential Equations and such.
Your response would be a great help, thanks!
I messed up initially and found the degrees, then got some help and figured out what I did wrong and the formula needed to find the answer. But I’ve mixed up the numbers a few times and got different answers, so I’m unsure which is correct.
Here is my work and answer. Can anyone tell me if I did something wrong or if I’m right?
Can Precalculus and Trigonometry be counted toward business related subject requirement under Mathematics? I thought I had to take around 24 semster units to fulfill the 150 credits requirements for CPA licensure. BUT! I just intensely analyzed all my previous schools transcripts and found out that I had taken "Precalculus" and "Trigonometry" math courses at college. I know Calculus can be counted, I have confirmed with CBA long time ago.
If these courses can be counted towards business related subject requirement under Mathematics, I only need to have 13 semester units! I will email the Board of Accountancy next Monday but before I do that I wanted to ask you guys if any of you have any ideas. I am so excited! Plus I found some hidden courses that I took from university-extension courses.
By the way, who made california cpa educational requirements? it is so complicated and you can get many different results!
If tan(x)=-1/2, pi/2<x<pi, tg(y)=3, 0<y<pi/2, then sin(x+y) equals:
Hi Reddit! As the title suggests I'm absolutely so lost right now. I'm currently enrolled in a precalc class and this is the second semester of a two part class at my community college. The class is about two hours given it's a summer enrollment which I took because I want to be done with math as soon as possible. For the syllabus day we basically spent an hour and a half discussing the syllabus and with what little time we started the lecture. Immediately I had no idea what was happening and was so lost. She (the professor) started listing tons of Trig Identities including Pythagorean, Reciprocal, Cofunction, etc. I definitely struggled with this topic in high school as math was quite literally my worst subject and still is. The previous semester we did cover trig identities and whatnot, but due to quarantine I actually missed a lot of my classes because of the devolved sleep schedule I adopted as a result of being at home all of the time. The chapters covering Trig Identities were th... keep reading on reddit ➡
A project that I have been working on for about two years now is finally complete. TrigCalc is a step-by-step trigonometry calculator that was created with the intent of helping trigonometry students and up. The list of all calculators are shown below:
- Right Triangles
- Oblique Triangles (non-right triangles)
- Trigonometric Identities
- Coterminal Angles
- Supplementary Angles
- Complementary Angles
- Trigonometric Functions
I really hope this project helps many! TrigCalc will gradually include more and more features so your recommendations and feedback are greatly appreciated!

Fuck you trigonometry you slimy little bitch
I've been following through Khan Academy and they've had pretty good descriptions for everything up until now. I've gotten to the above question and really had no idea where to start. Hint 2/4 tells me to "Multiply both sides by sin(B)" but doesn't give any explanation as to why that's what I need to do, and the videos up until this point used a different method since 30-60-90 triangles were being used for the examples.

Taking the zero on the assignment
so i have this graph and this is a sin graph. (a*sin(bx+c)+d)
so my question is: Can I write an equation for this graph but instead of sin, using cos?
PQ is tower on horizontal plane where A,B are points & AB=32 ft. QAB = 90°. cotPAQ = 2/5, cotPBQ = 3/5. Find height of tower.
Please help in solution. This problem is from loney's plane trigonometry.
What’s a good trigonometry book?
I’m interested in a book on trigonometry (including circular and hyperbolic) that goes beyond undergraduate level service class understanding to provide a intuitive feel for the six main trig functions from an analytical pov as well as geometric. I have “The Geometry of Special Relativity” by Tevian Dray already.
The picture. I was given a hint that said if I set the radius of the circle in the diagram to be 1, I can conclude that an angle of 60 degrees is subtended by an arc larger than 1, but I'm not sure how I would write the proof.
I'm looking for a book that can shows me the basics and maybe the not so basic trigonometry, it doesn't need to be a super simple one, just one that explains everything it talks about. Thanks in advance guys
Jim and Joe are twins on each end of a field. Jim has his kite in the air out on 45 m of string and the string makes an angle of 30 degrees with the ground. Joe determines that the angle of elevation from his location to the kite is 20 degrees. How high is the kite, how far apart are they and how far is the kite from Jim.????
I get that you can use the whole unit circle idea that the y-coordinate on the circle is the value for sin(θ), but didn't we base this whole idea on drawing a right triangle within the unit circle such that the hypotenuse is 1?
Well if θ = 90°, then we're not dealing with a right triangle anymore, so why are we still allowed to say that sin(θ) is equivalent to the y-coordinate when θ = 90°? (I also am a visual learner, so if a visual explanation is possible here, that would be greatly appreciated)
i got an A in the class ! i dont have to retake it for summer , that means for my last year in fall i can take calculus . i am so excited ! i have never been good at math , but i actually understood the work because you all helped me and put up with my constant questions . thank you all so much !
I feel like I'm missing something obvious, but I am completely stuck on this. The previous problems had me show that cos(x+y)cos(x-y) = cos^2 x cos^2 y - sin^2 x sin^2 y, and that sin(x+y)sin(x-y) = sin^2 x cos^2 y - cos^2 x sin^2 y, and I am supposed to use those results.
I have 3 days to learn this thing for exam that will decide id i will pass this class , but our teacher given us barelly understandable hours long materials to learn from , and i cant understand single thing from it.
Can someone tell me where to start , what should i do or just link me up some youtube material that explain that subject well ? I understand definitions of sin , cos , tg and ctg and thats pretty much it
Aryabhata discussed the concept of sine in his work by the name of ardha-jya, which literally means "half-chord". For simplicity, people started calling it jya. When Arabic writers translated his works from Sanskrit into Arabic, they referred it as jiba. However, in Arabic writings, vowels are omitted, and it was abbreviated as jb. Later writers substituted it with jaib, meaning "pocket" or "fold (in a garment)". (In Arabic, jiba is a meaningless word.) Later in the 12th century, when Gherardo of Cremona translated these writings from Arabic into Latin, he replaced the Arabic jaib with its Latin counterpart, sinus, which means "cove" or "bay"; thence comes the English word sine.
A bit convoluted, and traces past the obvious Latin term, but I thought others... keep reading on reddit ➡
