Trigonometry Study Guide is a free educational mobile app By MobileReference.It helps students in grades HS practice the following standards HSF.TF.A.1,HSF.TF.A.2,HSF.TF.A.3.
1. HSF.TF.A.1 : Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle.
2. HSF.TF.A.2 : 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.
3. HSF.TF.A.3 : Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosine, and tangent for x, π + x, and 2π - x in terms of their values for x, where x is any real number..
