tanθ = 0.6114
I want to know how to use calculator for this question.
As I am asian who never been taught how to use calculator
Press (2nd)
arrow down and press (atan)
atan( will appear in the window enter .6114
atan(.6114) will become 31.4 (approximately)
This will be the answer in degrees.
If you want the answer in radians, arrow down to the lowre left corner and highlight rad.
the value of theta is given
Geno's answer is good but I will add that
arc tan and inverse tan are the same thing.
On the web2calc you use atan
but on many calcs the button looks like this \(tan^{-1}\)
