How to find all six trigonometric function values given one value (the secant) and the quadrant? Example: If sec θ = -2 and θ is in quadrant III, find all trigonometric function values for θ. Show Video Lesson
24 Ιουλ 2017 · This math video tutorial provides a basic introduction into trigonometry. It covers trigonometric ratios such as sine, cosine, and tangent.
In this video, we will be learning about trigonometric ratios. We'll start by introducing the three main ratios: sine, cosine, and tangent, and explaining wh...
Example 1 : Compare the sine, the cosine, and the tangent ratios for ∠A in each triangle below. Solution : By the SSS Similarity Theorem, the triangles are similar. Their corresponding sides are in proportion, which implies that the trigonometric ratios for ∠ A in each triangle are the same.
