:words:  sin :o/h.  Cos:a/h  tan:o/a

Opposite＝O

adjacent＝A

hhpotenuse＝H

(Example)

sin 50°＝0.766

Means that the opposite side is 76.6% of the

hypotenuseside.

cos12°＝0.978

Means that the adjacent side is9.787 of the hypotenuse side

tan43°＝0.932

Means that the opposite side is 93.3% of the adjust side
