WebNov 5, 2015 · The answer is -pi/4 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 … WebSteps for Finding the Tangent of a Circle. Step 1: Determine which length is missing in the figure.
