How do I use sin(), cos(), and tan() functions in iOS application? When I use this I didn’t get the correct value. Example:
double value=sin(90);
I got value: 0.893997 but expected value: 1. How can I fix this?
The problem is that it’s taking the sine of 90 radians, not degrees. Try
sin(M_PI_2)for 90°.
