How to eliminate the parameter with two trigonometric equations

The video tutorial explains how to eliminate parameters in equations by using the equation of a circle. It starts by discussing the limitations of using inverse functions for solving T and introduces the circle equation X^2 + Y^2 = R^2 as a more effective method. The tutorial then demonstrates how to derive the value of R using trigonometric identities, specifically cosine squared and sine squared. Finally, it concludes by explaining how the graph of the equation represents a circle, not a line or quadratic.
