WebThe trigonometric ratios can be used to solve 3-dimensional problems which involve calculating a length or an angle in a right-angled triangle. It may be necessary to use Pythagoras'... WebTrigonometric ratios are not only useful for right triangles, but also for any other kind of triangle. In this unit, you will discover how to apply the sine, cosine, and tangent ratios, along with the laws of sines and cosines, to find all of the side lengths and all of the angle measures in any triangle with confidence.
