Now consider the angle CBA. Let's call it the angle of slope. It's tangent is CA/BC = m/1 = m. Therefore, the slope is the tangent of the angle of slope.

You need to convert the angle to radians before calling the appropriate method. Since 360 degrees = 2 pi radians, multiplying the angle by PI/180 will give you the appropriate value to pass along to the trig function.
