Trigonometric Ratios and Calculations

This video tutorial covers the use of trigonometric ratios to solve for sides of right triangles. It explains the importance of setting calculators to degree mode and demonstrates solving problems using sine, cosine, and tangent ratios. Three example problems are worked through, illustrating how to identify and apply the correct trigonometric ratio based on given triangle sides and angles.
