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...

An equation that has an infinite number of solutions is an identity.  sin-1x = cscx-1.  sin (x+y) = sin⁡ x + sin ⁡y.  If 0° ≤ θ ≤ 90°, then cosθ = sin (180° – θ).  cos (cos-1x) =...
