Can anyone show me how to defrentiate these 4 functions please
(3x^2-4x)^3
(x^2+2)(2x^3-5x^2+4x)
sqrt X - 3rd square root x not 3(sqrt x) but the 3 is very small and close to the square root sign
and 3x/x^2+4
*
hopefully you know the power rule for derivatives.
are you aware of the chain rule?
it says
here, your and your
an example:
here, apply the product rule(x^2+2)(2x^3-5x^2+4x)
it says (if and are functions of ), then
here, your and your
note that you can write the radicals as powers to obtain the following
sqrt X - 3rd square root x not 3(sqrt x) but the 3 is very small and close to the square root sign
now apply the power rule to find the derivative
two main options here.and 3x/x^2+4
(1) write as and use the product rule with and . note that you need the chain rule to find
(2) use the quotient rule:
your and are the same as above
