For example,
- sin 33.35 = 0.5523 in degree
- sin 33.35 = 0.9347 in radian
As Xcode gives answers by default in radian.
So is there any way to get answer in degree ???

Yes, you multiply radians by a constant,
180/pi, to get degrees. That’s because there are2 * piradians in a complete circle of 360 degrees (so half a circle ispiradians and 180 degrees).Just keep in mind that’s a conversion you have to apply to the input of the sine function (the angle), not the output (which is a length).
The
piconstant can be used by includingmath.hand using theM_PIsymbol.
