The video tutorial explains how to determine the six trigonometric functions of an angle, Theta, using a right triangle. It begins by emphasizing the importance of drawing a triangle and identifying its sides. The Pythagorean Theorem is used to find the missing side. The tutorial then calculates the sine, cosine, and tangent functions, followed by their reciprocal functions: secant, cosecant, and cotangent. The process of rationalizing denominators is also demonstrated. The tutorial concludes with a summary of the steps involved in finding all six trigonometric functions.
