# Calculus 2 : Parametric, Polar, and Vector

## Example Questions

### Example Question #65 : Parametric Form

Convert the following parametric equation to rectangular form:

Explanation:

To convert from parametric to rectangular coordinates, we must eliminate the parameter by finding t in terms of x or y:

We will start by taking the exponential of both sides of the equation . Recall that .

Therefore we get,

.

Now, replace t with the above term in the equation for x:
