Hello,

I'm teaching myself Calculus, as I see a need for it in my future career. I started watching some basic calculus videos from MIT, but there are a few questions I would like to ask:

I am aware of the following rule:

$\displaystyle \frac{dy}{dx} = nx^{n-1}$

However, I don't understand how to apply it to a function such as this:

$\displaystyle y = 1 - x^2$

Or this:

$\displaystyle y = (x^3 - 2x^2)$

I would appreciate any assistance!

Thanks,

Austin
