How to use the inverse tangent without a calculator

👉 Learn how to evaluate the inverse of reciprocal trigonometric functions. Recall that the reciprocal trigonometric functions are given by the ratio of 1 and the corresponding trigonometric function. When an angle is unknown but the value of one of the reciprocal trigonometric functions of the angle is known, we can evaluate the value of the angle by first converting the given reciprocal trigonometric function to the corresponding trigonometric function and then using the inverse trigonometric function of the obtained trigonometric function.

For instance, if we know that sec x = a/b where x is unknown and a, b are known, then we an evaluate x by first expressing sec x = 1 / cos x = a/b, this means that cos x = b/a and thus x = arccos (b/a).
