TRIGONOMETRIC RATIOS - VEDANTU

Trigonometric Ratios Definition. Trigonometric ratios help us to find missing angles and missing sides of a triangle. To be more specific, they are used in right- angled triangles, the triangles with one angle equal to 90 degrees. In case you might not know what, a right-angled triangle is, here’s a little information! Consider a right-angle triangle ABC, with its three sides …

ALGEBRA PRECALCULUS - WHAT DO THE TRIGONOMETRIC RATIOS ...

First I had the simple notion that the trignometric ratios are ratios of sides of a triangle. But when $\sin(0) = 0 , \cos(0) = 1 $ what do they mean? I had read about the unit circle definition and I thought that the unit circle definition was just a nice way to represent the triangle inside a circle and in the process simplify the calculation of ratios at various angles.
