Answer 1

Math trig functions nearly always use radians. There are 2π rads in a circle. The conversion from degrees to radians is:

degrees * M_PI / 180

// To get π constant
#define _USE_MATH_DEFINES
// before #include math...

Your angle should also probably be a floating type, so it can be used to store the converted value.

Answer 2

Cause these functions take a radian angle , you must transform from degree to radian
Radian = Degree * ( PI / 180 )
