WebArctangent (aka inverse tangent or tan^-1) is the inverse operation of tangent. Since tangent corrospondes an angle to the slope of its terminal ray, arctangent corrospondes a certain slope to the angle that a line of the slope will form in the unit circle. Example: tan (45°) = 1 ==> arctan (1) = 45°. One should take note that, as with all ... WebMar 13, 2015 · Step 1-. Decide from where you are going to measure your angle.
