A quick cheat-sheet of math stuff.
Remember: \(\sqrt{x}=x^(\frac{1}{2})\)
General formula:
\(y-y_1 = m(x-x_1)\)
where you have the points
\((x_1, y_1)\)
The subscripts just indicate the point you are given, i.e. specific \(x\) and \(y\) points as opposed to general \(x\) and \(y\) points.
Derivative : The slope of a line.
\(\frac{d}{dx}(\frac{u}{v}) = \frac{v(\frac{du}{dx})-u(\frac{dv}{dx})}{v^2}\)
