Christopher AgrestaTo find the derivative of ( y = \frac{5}{(2x)^2} + 2\cos(x) ), apply the quotient rule and the chain rule for differentiation. The derivative is ( y' = -\frac{20}{(2x)^3} - 2\sin(x) ).

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.
