Master Evaluating the double angle for Sine, Cosine and Tangent, given an angle and constraint ex 3

The video tutorial explains how to evaluate the double angles of sine, cosine, and tangent given an equation and a constraint. It begins by introducing the concept and the need to create a right triangle. The tutorial then demonstrates the calculations for sine, cosine, and tangent of double angles using specific formulas. Each step is explained in detail, including the use of the Pythagorean theorem and the manipulation of fractions. The video concludes with a summary of the evaluation process.

Describe the process of calculating cosine of two Theta using the cosine squared and sine squared formula.

What is the formula for tangent of two Theta, and what steps are involved in its calculation?

Summarize how to evaluate for the double angle of sine, cosine, and tangent when given an equation and a constraint.
