Every word … WebTo create such sine wave chart first what you need is to prepare data. Generate data for the sine wave. Start from writing angles from 0 to 360 degrees. Next you need to convert degrees to radians. To do that just use =RADIANS (A2) and drag down. Next thing you need to do is convert radians to sine value. Here's the formula for you.
