Online arctan(x) calculator. Inverse tangent calculator.
The arctangent function is the inverse function of y = tan(x).
arctan(y) = tan-1(y) = x+ kπ
For every
k = {...,-2,-1,0,1,2,...}
For example, If the tangent of 45° is 1:
tan(45°) = 1
Then the arctangent of 1 is 45°:
arctan(1) = tan-1(1) = 45°
y | x = arctan(y) | |
