Given a point find the six trigonometric functions of the angle

The video tutorial explains how to evaluate all six trigonometric functions given a point not on the unit circle. It covers plotting points on a grid, forming triangles, defining central angles, and using the Pythagorean theorem to find the hypotenuse. The tutorial also demonstrates calculating sine, cosine, and tangent ratios, as well as their reciprocal functions, with a focus on rationalizing denominators.
