The angle in radians for which you want the sine.
The SIN function calculates the sine of an angle provided in radians. If your angle is in degrees, you must multiply it by PI()/180 or use the RADIANS function to convert it before calculating.
=SIN(PI()/2)→1Calculates the sine of PI/2 radians (90 degrees), which is 1.
=SIN(RADIANS(30))→0.5Converts 30 degrees to radians and calculates the sine, which is 0.5.
Prepare your angle
Ensure your angle is in radians. If it is in degrees, use the RADIANS function.
Enter the formula
Type =SIN(number) into a cell, replacing 'number' with your value or cell reference.
This usually happens because the input is in degrees instead of radians; use the RADIANS function to convert it.
