Question

After writing \(x=f(t)\) and \(y=g(t)\), what should be found separately?

Options

• \(x+y\) and \(x-y\)

• \(\frac{dx}{dt}\) and \(\frac{dy}{dt}\)

• Only \(\frac{dy}{dx}\)

• Only \(\frac{dt}{dx}\)

Answer 1

The derivatives \(\frac{dx}{dt}\) and \(\frac{dy}{dt}\) must be calculated separately. They are then used in the parametric derivative formula.
