Best ResponseYou've already chosen the best response.1Woops the 2 should still be there on the second term. A 1 came down from the power rule.

Best ResponseYou've already chosen the best response.1Yes that's the correct derivative. Don't use quotient rule, easier to use power rule.\[\large \left(\frac{1}{2y}\right)'\quad = \quad \left(\frac{1}{2}y^{1}\right)' \quad = \quad \frac{1}{2}y^{2}\]
