Step-by-step explanation:

Given

Required

Write the equivalent cosine function

The general formula is:

Where

Substitute for amplitude in

Substitute 3 for period in

Multiply both sides by b

Divide through by 3

Hence;

becomes

welll its a very hard question but ill

step-by-step explanation:
