Evaluate the trig function of cosine and inverse tangent

👉 Learn how to evaluate an expression with the composition of a function and a function inverse. Just like every other mathematical operation, when given a composition of a trigonometric function and an inverse trigonometric function, you first evaluate the one inside the parenthesis.

We can evaluate the composition of a trigonometric function and an inverse trigonometric function using a calculator, the unit circle of the quadrants' triangle. It is important when computing the inverse of a function that the input is within the domain of the function and the output is within the range.

you have been such a big help in my pre-cal class in college. My school is online and pretty much have to teach myself at this point. Your videos have been a life saver.

Thanks for the help. I am a senior in my high school 😀

I think that arctan is in quadrant 2 and 4
