To find the derivative of ( y = \frac{1}{x^7} ), you can use the power rule for differentiation, which states that if ( y = ax^n ), then ( \frac{dy}{dx} = anx^{n-1} ). Applying this rule to the given function, we have:

[ \frac{dy}{dx} = -7x^{-8} ]

So, the derivative of ( y = \frac{1}{x^7} ) is ( \frac{dy}{dx} = -7x^{-8} ).

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.
