Evaluate the six trig functions given a point in fractions

The video tutorial covers evaluating trigonometric functions using both the unit circle and right triangles. It explains how to plot points, create triangles, and apply the Pythagorean theorem to find the hypotenuse. The tutorial demonstrates calculating sine, cosine, and tangent, and emphasizes simplifying expressions and rationalizing denominators. It concludes with finding reciprocal trigonometric functions: cosecant, secant, and cotangent.
