Use the unit circle to explain symmetry (odd and even) and periodicity of trigonometric functions. F.TF.3 Use special triangles to determine geometrically the values of sine, cosine, tangent for , , and , and use the unit 3 4 6 circle to express the values of sine, cosine, and tangent for x, x , and 2 x in terms of their values for x, where x is any real number. F.TF.8 Instructional Notes/Strategies Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle. F.TF.4 F.TF.4 Evidence / Assessments of learning Use the unit circle to explain symmetry (odd and even) and periodicity of trigonometric functions. Prove the Pythagorean identity sin2(θ) + cos2(θ) = 1 and use it to find sin(θ), cos(θ), or tan(θ) given sin(θ), cos(θ), or tan(θ) and the quadrant of the angle. Differentiation www.Mathtv.com/videos_by_topic Define the trigonometric ratios in the coordinate plane Define trigonometric functions in terms of the unit circle Construct a tangent line from a point outside a given circle to the circle. Describe how do you convert between radians and degrees.
