Convert degrees to radians: ( text{radians} = text{degrees} times frac{pi}{180} )
Example: (45^circ rightarrow 45 times frac{pi}{180} = frac{pi}{4})
Example: (90^circ rightarrow 90 times frac{pi}{180} = frac{pi}{2})
Example: (180^circ rightarrow 180 times frac{pi}{180} = pi)
If you need degrees from radians: ( text{degrees} = text{radians} times frac{180}{pi} )
