RED – y = cos(x) BLUE – y = sin(x) GREEN – y = tan(x) VIOLETE – y = atan(x) 100% by me. Idea is by me too.
Black frame is start and end of 3 functions: cos(x) sin(x) tan(x) [scroll] cos(x) returns value from -1 to 1 sin(x) returns value from -1 to 1 tan(x) returns value from -infinity to infinity I don't know what returns atan(x). [scroll] I only know about atan(x) is returns z in tan(z) and x = tan(z)
