## How to calculate degree? | Angles are are a measure of X/Y, same units, therefor a dimensionless value ,(which is what Tan(x) gives you.) Angle on a chart is meaningless. We have price vs time. What is the angle of going 5 miles in 10 minutes? Meaningless! You can only calculate a slope on a chart. |

If tan(X) = 20.

What function use to find X ?

Thank you
