What are the six trigonometric functions

The video introduces the six trigonometric functions, focusing on their meaning and significance. It explains how these functions are based on ratios, particularly in right triangles, and highlights the importance of identifying angles. The video covers the basic functions: sine, cosine, and tangent, as well as their reciprocal functions: cosecant, secant, and cotangent. The concept of SOHCAHTOA is also introduced as a mnemonic to remember these functions.
