How to use a triangle to evaluate the six trig functions for an angle

The video tutorial explains how to evaluate the six trigonometric functions using a triangle instead of the unit circle. It begins by determining the hypotenuse using the Pythagorean theorem and simplifying the result. The tutorial then calculates sine, cosine, and tangent based on the triangle's sides, followed by the reciprocal functions: cosecant, secant, and cotangent. The process includes rationalizing denominators and simplifying expressions to reach the final answers.
