cos problem realy easy

is there a function that does use radians. or can someone tell me the conversion i''ve forgotten it.
radian = degree * pi / 180
degree = radian * 180 / pi
edit: all c function use radian.

float angle1 = 45; //degreesfloat sine //sinus;float radians //radians;float angle2 //degrees;sine = sin(angle1 * 3.141/180); //convert to radians, c wants radians, not degrees radians = asin(sine); //c will return the angle in radiansangle2 = radians * 180 / 3.141; //reconvert to degrees [edited by - Wildfire on January 31, 2003 4:54:56 AM]

what''s the function for inverse cosine?
You know, it would be helpful if you specified a language.
