@GenericCoder Thanks man I appreciate all your help :)

@chaosdimension100 You might also want to go to k h a n a c a d e m y . o r g

Yes sure I will send you it as pm no problem :).

@GenericCoder Excatly what ive been thinking- break the triangle into 2 right angle triangles on either side of the quadrants. But do you add your two answers together or subtract them. And yea you cant use the right angle triangle rule becaue it breaksdown on angles greater than 90 degrees and Im familiar with the cosine and sine rules.
do you have a specific video that explains my questions that i can maybe watch? cheers
-
No not exactly lets say the triangle has a side more than 90 degrees meaning not right angle triangle(oblique triangle) we can either form right triangles on each on 3 sides and calculate each side or we can use sine law or cosine law in order to solve for them.
Continue with the playlist more of trigonometry you'll understand more and more :).

@GenericCoder Thats what ive been thinking for a long time but wasnt sure that was the answer. So if I am correct the triangle doesnt have an angle of greater than 90 degrees it would start from zero again but can be described as having 180 degrees for the sake of periodic motion. Is this the way to think about it?
-
You can contruct a triangle but on the opposite side in the cartesian coordinate it would have negative x axis. This is really important aspect especially in physics.
I hope this makes sense.
-
The thing i dont mostly understand i guess is how are you supposed to get a triangle with an angle of 90 or more. This is whats confusing me. I guess the values for angles above 90 degrees are used more to show the period nature of trig functions rather than to describe the triangles themselves. Am I right can someone please explain where I might be getting confused here
thanks

@MrPinkFlippers a right triangle is a triangle having one right angle ... got to learn your math terms :D

I like how a YouTube video helps me learn better than my teacher who's been teaching for more than 20 years.

You shuold be a millionare by the way you teach, i try to listen to my professor and he doesnt help, i mean hes good i just feel embarassed for him to go over the topic again to look stupid... because on the last homewrok assignment everyone was like o that took me 20 minutes to do... yeah not for me.... and my precalc teacher in high school got fired because she was so awful so i never learned any of this unit circle stuff well enough. you are the man. THE MAN!
