Answer 2

Trigonometric Ratios
"Trigon" is Greek for triangle, and "metric" is Greek for measurement. The trigonometric ratios are special measurements of a right triangle (a triangle with one angle measuring 90o). Remember that the two sides of a right triangle which form the right angle are called the legs, and the third side (opposite the right angle) is called the hypotenuse.

There are three basic trigonometric ratios: sine, cosine, and tangent. Given a right triangle, you can find the sine (or cosine, or tangent) of either of the non-90o angles.



Example:

Write expressions for the sine, cosine, and tangent of A.
