Measurement of Angles. Definitions 1) Angle - two rays joined at a common point called a vertex point. 2) Revolution - a common unit used to measure large angles, like the number of revolutions a car wheel makes traveling at 10 mph. 3) Degree - a common unit used to measure smaller angles. There are 360 degrees in 1 revolution.

Period of trig functions: Even and Odd trig functions: cosine and secant are even. sine, cosecant, tangent and cotangent are odd functions. Coterminal Angles: Two angles are said to be coterminal if they have the same initial and terminal sides. Example: The following are coterminal. 20º, 380º, 740º, 1100º, -340º, -700º, -1060º . . .

Assist students in learning how to use the calculator to find trig ratios and to use the ratios to solve problems. In order to facilitate understanding, have students read information from a standard trig table. For example, in order to solve , students need to understand that there is one angle which has the same decimal ratio as 12 divided by 17.

TRIGONOMETRIC RATIOS: Ratios of the lengths of the sides of a right triangle (related to the acute angles) The three most common ratios are . SINE, COSINE, & TANGENT. EXAMPLE 1 Find sin A, cos A, tan A, sin B, cos B, and tan B. Express each ratio as a fraction. EXAMPLE 2 Find sin S, cos S, tan S, sin E, cos E, and tan E.

Consider calling on students to provide a few of the trig function values for the acute angles. We have already seen the right triangle definitions of sine, cosine, and tangent; the identity tan θ= sin θ cos θ ; and the values of sine, cosine, and tangent when evaluated at the angles 30˚, 45˚, and 60˚.
