Evaluate for Theta Between 0 and 2pi

👉 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).

Thank you Mr. McLogan!! My final exam for precalculus is tommorow and this has been a struggling problem for me when I try solve it and you explained so simplistically and patiently. I love this video! Keep making more

Just watched this, and subscribed. Amazing!
Our books don't teach why we had to subtract from pi in case of sinx, while we subtract from 2pi in case of cosx. This explained everything.

What a complicated way to explain. Just use special triangles for God's sake. You're not allowed the unit circle in a test.
