The Importance of Ratios in Trigonometry

The trigonometric functions are based on properties of right triangles. Right triangles have one 90-degree angle on the interior, two shorter sides and a longer, slanted side called the "hypotenuse." In trigonometry, the concern is with an unknown angle....

Q:
What are the other trig ratios ?

A:
We know that cos^2 x + sin^2 x = 1. (1/8)2 + sin^2 x = 1. sin^2 x = 63/64. sin x = sqrt(63) / 8. tan x = sin x / cos x = sqrt(63) / -1. cot x = 1 / tan x = -1/s...
