Using difference of two angles with tangent to evaluate

The video tutorial explains how to decompose the angle 17π/12 into two angles to evaluate its tangent using the tangent difference formula. It covers the evaluation of tangent for angles 9π/4 and 5π/6 using the unit circle, rationalizing denominators, and simplifying expressions by multiplying with conjugates. The tutorial emphasizes understanding the unit circle and algebraic manipulation to solve trigonometric problems.
