- For the following graph, write an equation (with the smallest phase shift) in the form of:
(i) y = a sin b(x - c) + d
(ii) y = - a sin b(x - c) + d
(iii) y = a cos b(x - c) + d
(iv) y = - a cos b(x - c) + d
- A sinusoidal curve has a minimum point at and the closest maximum point to the right is . Determine an equation of this curve.
