Evaluating an expression using the composition of trig functions

The video tutorial explains the order of operations in algebra, focusing on parentheses and exponents. It then transitions to trigonometry, specifically the sine inverse function and its domain constraints. The instructor demonstrates how to calculate angles for sine inverse of 1/2, emphasizing the importance of understanding angle constraints. The tutorial concludes with applying these constraints to find the final answer, highlighting the cosine function and its role in trigonometry.
