Output:
The cosine of -1.000000 is 0.540302
The cosine of 0.000000 is 1.000000
Calculates the trigonometric cosine function of a single precision float-
ing-point value.

float cosf (float x);
x
Returns the cosine of x in radians in the ranges of -1 to 1 inclusive.
A domain error will occur if x is a NaN or infinity.
