The video tutorial covers the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. It begins with an introduction to these functions and their definitions. The tutorial then explains the properties of right triangles, including the hypotenuse, opposite, and adjacent sides. The Pythagorean theorem is applied to calculate side lengths. The video further explores trigonometric ratios, defining sine, cosine, and tangent, and concludes with an explanation of reciprocal functions: cosecant, secant, and cotangent.
