Hi Guys, I was wondering how one would write a C program that calculates the value of a cosine function without using any library functions from <math.h>
I need the outputs to turn out like this
Case 1: cos(-1.000) = 0.540302303792
Case 2: cos(1.000) = 0.540302303792
Case 3: cos(1.500) = -0.125000000000
Case 4: cos(2.000) = -0.422222222222
Case 5: cos(2.000) = 1.000000000000
