F.TF.1 High School - Functions Extend the domain of trigonometric functions using the unit circle. Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle. 0
F.TF.2 High School - Functions Extend the domain of trigonometric functions using the unit circle. Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle. 0
F.TF.3 High School - Functions Extend the domain of trigonometric functions using the unit circle. (+) Use special triangles to determine geometrically the values of sine, cosine, tangent for p/3, p/4 and p/6, and use the unit circle to express the values of sine, cosines, and tangent for x, p + x, and 2p – x in terms of their values for x, where x is any real number. 0
F.TF.4 High School - Functions Extend the domain of trigonometric functions using the unit circle. (+) Use the unit circle to explain symmetry (odd and even) and periodicity of trigonometric functions. 0
F.TF.5 High School - Functions Model periodic phenomena with trigonometric functions. Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.? 0
F.TF.6 High School - Functions Model periodic phenomena with trigonometric functions. (+) Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed. 0
F.TF.7 High School - Functions Model periodic phenomena with trigonometric functions. (+) Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology, and interpret them in terms of the context.? 0
F.TF.8 High School - Functions Prove and apply trigonometric identities. Prove the Pythagorean identity sin^2(?) + cos^2(?) = 1 and use it to find sin(?), cos(?), or tan(?) given sin(?), cos(?), or tan(?) and the quadrant of the angle. 0
