Question

If required, in terms of which variables may the final answer be expressed instead of the parameter?

Options

• Only the derivatives

• Only \(a\) and \(t\)

• Only \(t\) and \(u\)

• \(x\) and \(y\)

Answer 1

The final answer may remain in terms of the parameter. If the question requires conversion, it should be expressed in terms of \(x\) and \(y\).
