Hello, I am having trouble understanding how to differentiate this polynominal.
Can someone please outline the steps. I want to use the Newton and Leibniz method rather than the first principles formuls.
Thanks kindly for any help.
4√x +4/x

4√x +4/x
thanks, I can get the second term, but still cannot get the correct answer for the first term (4√x).
What is the answer for that first term ? Then I will be able to understand.
Thanks
(for the first term, I am getting 2/x^1/2, but I dont think that is correct.)
$\displaystyle \displaystyle \frac{d}{dx}\left(4x^{\frac{1}{2}}\right) = \frac{1}{2}\cdot 4x^{\frac{1}{2} - 1}$
$\displaystyle \displaystyle = 2x^{-\frac{1}{2}}$
$\displaystyle \displaystyle = \frac{2}{x^{\frac{1}{2}}}$
$\displaystyle \displaystyle = \frac{2}{\sqrt{x}}$.
So you are correct.
