Trigonometric Functions: Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent

The video tutorial introduces trigonometry, focusing on right triangles and their properties. It explains the trigonometric functions sine, cosine, and tangent, using the mnemonic SOHCAHTOA. The tutorial also covers the reciprocal functions cosecant, secant, and cotangent. It concludes with an exploration of special triangles, specifically the 30-60-90 and 45-45-90 triangles, and their trigonometric values.

How do the lengths of the legs of a triangle change as the angle increases?

What are the definitions of cosecant, secant, and cotangent in relation to sine, cosine, and tangent?

Describe the process of finding the trigonometric functions for a triangle with sides of 5, 12, and 13.
