How to find the composition of inverse functions

The video tutorial discusses the composition of functions, focusing on the inverse sine function and its domain and range. The instructor compares the current problem with a previous one, explaining how to evaluate the inverse sine of a value and the importance of ensuring values fall within the correct domain and range. The tutorial emphasizes that sine and inverse sine functions cancel each other out, leading to the original input value. Key takeaways include understanding the domain and range of trigonometric functions and the conditions under which inverse operations can be applied.
