- 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.
