Question

how do I find the derivative of 4x/(X^2+1) using the rules?

Answer 1

\[[\frac{t}{b}]'=\frac{bt'-b't}{b^2}\]

Answer 2

will only the quotient rule work?

Answer 3

the top uses the power rule; the bottom uses the power rule; you can negate the bottoms exponent and use the product rule f its easier

Answer 4

\[t(b^{-1})=t'b+tb'\]
