Excel review: trigonometric functions. Tips • When working with angles, Excel does not recognize degrees. Any angle given in degrees needs to be converted into radians before doing any calculations with it: Example: convert 30 degrees into radians: Radians= 30 x Pi/180 = 30 x 3. 14/180 = 0. 63 rads • To determine the sine value of 0. 63 rads, write the following in excel: =sin(0. 63) The same applies to other trigonometric functions
