Lets write a C program to convert angle from Degree to Radian.
radian = degree x (M_PI / 180.0);
where M_PI is a constant present in header file / library file math.h and its approximately equal to 3.14;
Note: Trigonometric Ratios like Sin, Cos, Tan etc take radian value as input and not degrees. So its important to learn how to convert angles from degree to radian.

#include<stdio.h> #include<math.h> int main() { float degree, radian; printf("Enter angle in Degrees\n"); scanf("%f", °ree); radian = degree * ( M_PI / 180.0 ); printf("Angle in Radian is %f\n", radian); return 0; }
Output 1:
Enter angle in Degrees
90
Angle in Radian is 1.570796
Output 2:
Enter angle in Degrees
360
Angle in Radian is 6.283185
