Yes, I'm aware that you need to supply radians.
Everthing appears to be fine when going from 0 to 45 degrees but at 90
degrees, the tangent returns -22877334.
I've even tried doing the tan(x) = sin(x) / cos(x) approach.

Just to make sure, you are aware those functions from math.h take
arguments in radians, and not degrees, right?

For some reason, using standard trigonometric functions are not
behaving as they should once you hit 90 degrees. I'm not importing
another framework/library and assuming the ones I'm calling are the
same ones found in the standby "math.h". The functions return
correct values until you reach odd multiples of 90 degrees when one
should not be getting finite values as I am getting.
I'm assuming that the functions that I am using are basically from
math.h and using a Taylor-like numerical method.
Any suggestions or alternatives? I've looked/searched through the
documentation and have not found any other options.
Thank you for your time.
