If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.

### Section 9.1 : Parametric Equations and Curves

12. Write down a set of parametric equations for the following equation.

$y = 3{x^2} - \ln \left( {4x + 2} \right)$ Show Solution

There really isn’t a lot to this problem. All we need to do is use the “formulas” right at the end of the notes for this section.

A set of parametric equations for the equation above are,

\begin{align*}x & = t\\ y & = 3{t^2} - \ln \left( {4t + 2} \right)\end{align*}
