# Parametric derivative online calculator

Let's define function by the pair of parametric equations:

, and a≤t≤b,

where x(t), y(t) are differentiable functions and x'(t)≠0. Then the derivative is defined by the formula:

, and a≤t≤b,

where
- the derivative of the parametric equation
y(t)
by the parameter t and
- the derivative of the parametric equation
x(t),
by

the parameter t.

Our online calculator finds the derivative of the parametrically derined function with step by step solution. The example of the step by step solution can be found here.
