The video tutorial explains how to find all six trigonometric ratios for a right triangle with given side lengths. It begins by drawing and labeling the triangle, then uses the Pythagorean theorem to find the missing side. The tutorial proceeds to calculate the sine, cosine, and tangent of angle a, followed by their reciprocals: cotangent, secant, and cosecant. Finally, it discusses rationalizing the denominators of these ratios.
