Question

When \(x\) and \(y\) are expressed separately as functions of the same third variable \(t\), which equations are obtained?

Options

• Cartesian equations

• Differential equations

• Parametric equations

• Polar equations

Answer 1

When \(x=f(t)\) and \(y=g(t)\), the equations are called parametric equations. Both variables are expressed in terms of the same third variable.
