An angle is in standard position when the vertex is at the origin of a coordinate system….

An angle is in standard position when the vertex is at the origin of a coordinate system. The phase shift of ƒ(x) = 2 sin (2x – π/3) is π/3. The angle θ in radians is in standard position with the terminal side in the second quadrant. The reference angle of θ  is  π – θ. The measure of one radian is more than 50 times the measure of one degree. The amplitude of the graph of y = -7 tan (πx) is  7.
