Hi, I have to calculate TAN y angle and I on my scientific calculator i would
do 8.391/14.142 *inv tan and get 30.68 degrees. I cannot seem to find out how

Calculating inverse tangent (tan^-1) in Excel

1. Enter the values for your calculation in separate cells.
2. In a third cell, enter the formula "=ATAN(8.391/14.142)" (without the quotes).
3. Press Enter to get the result in radians.
1. To convert radians to degrees, multiply the result by 180/PI or use the DEGREES function.
2. For example, if the result of the ATAN function is in cell C1, you can use the formula "=C1*180/PI()" or "=DEGREES(C1)" to convert the result to degrees.

=ATAN(8.391/14.142)*180/PI()

Excel does trig in radians hence the 180/PI()
To save you remembering which way to do this use the conversion function
So to find the Tan of 60 or of degree value in A1
and to find the inverse tan (we oldies you we brought up with log 7 trig
paper tables call that the 'arc-tan')
=DEGREES(ATAN(A2)
best wishes
