`g(t) = 2/(3t^2)` Use the rules of differentiation to find the derivative of the function.
First rewrite the function as `g(t)=(2t^-2)/3`
Find the derivative of the function by using the power rule.
The derivative is `g'(t)=-4/(3t^3)`
Using a Quotient rule:
Simplify it all down,
Note that you should get the same answer if you used a product rule. If you don't, then check your answer because you must have made a mistake along the way.
