WebNov 5, 2015 · Alright, archtan / #tan^-1(x)# is the inverse of tangent. Tan is #sin/cos#. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4. Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
