/*------------------------------

Output

Enter the value of x (in degrees)

30

Enter the accuary for the result

0.000001

Sum of the sine series = 0.500059

Using Library function sin(30) = 0.500059

RUN 2

Enter the value of x (in degrees)

45

Enter the accuary for the result

0.0001

Sum of the sine series = 0.707215

Using Library function sin(45) = 0.707179
