# What is the equation of the tangent line of #f(x) =arcsin(cosx)# at #x=pi/4#?

Thus:

Equation should be written in point-slope form:

Forming a point-intercept:

This graph's appearance is very interesting, despite its lack of relevance, and it demonstrates why the absolute value signs were required.

The function cannot be graphed by the built-in Socratic grapher, but you can try it out yourself by going to https://tutor.hix.ai

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
