For any number between -1 and 1, your program calculates and outputs the arccosine and arcsine of the number in both degrees and radians. (Example: if you enter 0, arccosine is either 90 degrees or π/2 radians, and 270 degrees or 3π/2 radians.) For your convenience, your answers can be between 0 and 180 degrees (π).
This is what I've been doing. I know its wrong...The thing is it has to be like beginner MATLAB level language. i=-1;
