Tutorial - Given the Cosine of an Angle Determine the Double Angle for Sine, Cosine and Tangent

The video tutorial covers solving a trigonometric problem involving sine, cosine, and tangent of a given angle. It explains the constraints of the angle, the use of the unit circle, and constructing a triangle to find missing values. The tutorial then applies double angle formulas for sine, cosine, and tangent, demonstrating the calculations step-by-step. The session concludes with a Q&A to clarify any doubts.
