Learn how to evaluate an expression given the composition of two trig expressions

The video tutorial explains how to solve sine tan inverse problems by working from the inside out. It covers the concept of tan inverse, focusing on the angle constraints between -π/2 and π/2. The tutorial demonstrates calculating the tan inverse of 1, identifying the relevant angle as π/4 or 45 degrees. It also discusses the sine of π/4 and uses the unit circle to understand the relationship between angles and coordinates. The tutorial emphasizes understanding the Y over X coordinate relationship in the first quadrant.
