Chapter 10-2 Angles of Rotation (Day 2) Obj: Find Reference angles for an angle in standard position. Determine the values of the trigonometric functions for an angle in standard position Reference Angle - for an angle π in standard position, the reference angle is the positive acute angle formed by the terminal side of π and the x-axis. Examples: Find the measures of the reference angle for each given angle (tipβ¦sketch the angle) π) 150° π) β 130° π) 280° π) β100° π) β 245° π) 330° Determining the value of trigonometric functions for an angle π in standard position, use a point π with coordinates (π₯, π¦) on the terminal side of the angle. The distance π from point π to the origin is given by βπ₯ 2 + π¦ 2 Example: πππππ‘ π is a point on the terminal side of π in standard position. Find the exact value of the six trigonometric functions for π. π) π(β4, 3) (hint: Plot point and sketch a right triangle β find βrβ) π) π(4, β5) Homework (day 2) pg 703, 10 β 21, 34 β 41
