Trig and Logarithms
Compute sin, cos, log, exp.
Trig and Logarithms
The math.h header includes trigonometry functions like sin, cos, and tan, plus logarithm functions like log and log10.
They all take and return double values.
Angles Are in Radians
Important: the trig functions expect angles in radians, not degrees.
A full circle is 2 x pi radians. Half a circle (180 degrees) is pi radians.
