A timed sectional mock on this unit

Trigonometric identities and functions, and the inverse trigonometric functions with their properties.

Key formula
sin⁡2θ+cos⁡2θ=1,sin⁡(A+B)=sin⁡Acos⁡B+cos⁡Asin⁡B,sin⁡−1x+cos⁡−1x=π2\sin^2\theta + \cos^2\theta = 1, \quad \sin(A + B) = \sin A\cos B + \cos A\sin B, \quad \sin^{-1}x + \cos^{-1}x = \frac{\pi}{2}
