To find the derivative of ( y = \frac{1}{x^2} ), you can use the power rule for differentiation. The power rule states that if ( f(x) = x^n ), then ( f'(x) = nx^{n-1} ). Applying this rule to ( y = \frac{1}{x^2} ), we get:

[ \frac{dy}{dx} = -2x^{-3} ]

So, the derivative of ( y = \frac{1}{x^2} ) with respect to ( x ) is ( \frac{dy}{dx} = -\frac{2}{x^3} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
