3.1.2 2D Vector addition Write a function with comment blocks that performs 2D vector addition on two 2D vectors defined with polar coordinates. The function returns the 2D vector addition as a polar coordinate. This function must call rectPolarConv to perform any necessary rect polar conversion. Heres the prototype: void vectorAdd2D(double * mag1, double * ang1, double * mag2, double * ang2); mag1,mag2 are the magnitudes of the vectors 1 and 2 respectively. ang1,ang2 are the angles in degrees of the vectors 1 and 2 respectively. Their values are in the inclusive range of +/- 180 degrees The vector sum is returned in mag2, ang2. i.e mag2, ang2 are destroyed.
