**Calculating sine and cosine of an angle**

**=SIN(radians)**

But what to do when you know only degrees? Excel has also RADIANS function built-in =RADIANS(degrees) which convert degrees to radians. Just use it. Formula for sine with degrees is **=SIN(RADIANS(degrees)) **

The same for cose. Formula for cose with radians is **=COS(radians)**

When you know only degrees just use this formula **=COS(RADIANS(degrees))**

That’s the clever Excel trick how to convert degrees to radians and calculate sine and cosine for an angle. Trig functions are much easier thanks to Excel.
