Unformatted text preview: Evaluating the Trigonometric Functions Triangles to Know 30° 60° 1 2 3 45° 45° 1 1 2 Reference Angles Let θ be an angle in standard position. The reference angle associated with θ is the acute angle formed by the x-axis and the terminal side of θ. In Quadrant 1, θ is its own reference angle. In Quadrant 2, the reference angle is π - θ or 180° – θ, if working with degrees. In Quadrant 3, the reference angle is θ – π or θ - 180°, if working in degrees. In Quadrant 4, the reference angle is 2π - θ or 360° - θ, if working in degrees. Finding the values of the Trigonometric Functions of an Angle Start by finding the reference angle. Using the reference angle, find the point on the unit circle that is also on the terminal side of the angle. Apply the definition of the trigonometric functions to find the values. Example . 3 2 of functions tric trigonome the of value the Find π θ = What is the measure of this angle in degrees?...
