Trigonometric Concepts and Ratios

Mr. West explains trigonometric ratios, focusing on sine, cosine, and tangent, using the mnemonic SOHCAHTOA. He demonstrates how to solve for angles and side lengths in right triangles using these ratios. The video includes practical examples and encourages further exploration of trigonometry.
