Please create a function called d_to_r that takes a double as a parameter representing the degrees and returns the angle in radians. To get full credit you will need to make sure that your answer is within the +- 360-degrees (or +- 2PI)

Using C++

For basic conversion from degrees to radians use:

angle_in_radians = angle_in_degrees * PI/180.0;

Note: For PI add the following above int main(){

const double PI = atan(1.0)*4.0; // PI is a global constant

Example 1:

720-degrees should be converted to 0 degrees before converting it to radians

Example 2:

450-degrees should be converted to 90 degrees before converting it to radians

Example 3:

750-degrees should be converted to 30 before converting it to radians.
