err... there is no cotangent anywhere in math.h... or is there? does anyone know where there is a function for this?

Doesn't math.h have a tan() function?

x = 1 / tan (radians);

And if there is no tan() function just subsitute:

x = ( 1 / ( sin(radians) / cos(radians) ) );

Perhaps you should pick up a book calculus on your way home tomorrow because programming games need a LOT of math.

Sorry for the information most people don't want to face this but it's true. Math has a meaning in life.

Good Luck!

Where did Axiverse imply in any way whatsoever that he didn't think game programming involved math? Seems to me that he's explicitly asking about math.

As a matter of fact, asking for cotangent implies quite a bit of understanding of math :) You don't use that every day as a beginner!

of course if you're doing it that way you can simplify that to just:
x = cos(radians) / sin(radians);

Of course 1/tan is better like you said. weird, I never realized there's not a cot function. Learn somethin new everyday!

Yeah, I know the formula, but I was just wondering if there was a function, but thanks anyways!
