10.4 - 10.5 Trigonometric Ratios

(SOH-CAH-TOA) Trigonometry - a branch of mathematics that studies the relationships between the sides and angles of triangles. Trigonometric ratio - the ratio between two sides of a right triangle.

There are 3 "trig ratios" that we will study.

The ratios are called sine, cosine, and tangent.

They are abbreviated sin, cos, and tan respectively (locate these buttons on your calculator). abcABC sin x = opposite side hypotenuse cos x = adjacent side hypotenuse tan x = opposite side adjacent side

SOHCAHTOA

What do these trig ratios stand for?The mnemonic device to remember the 3 trig ratios is "SOH-CAH-TOA"

SOHCAHTOA

Example 1: Let's look at

Find the side opposite, side adjacent, and the

hypotenuse for Then write the sin A, cos A, and tan A ratios.
