Derivative check

  1. Mar 18, 2005 #1
    [tex]\frac{d}{dx} Xe^{lnX^2} = e^{lnX^2}+Xe^{lnX^2} \frac{1}{X^2} 2x[/tex]
    [tex]=\frac{X^2 e^{lnX^2}+Xe^{lnX^2}2X}{X^2} [/tex]

    is that correct?

    True enough, but since [tex]e^{ln(x^{2})}=x^{2}[/tex] there is an easier way to solve this..

    [tex]3x^2[/tex]

    is that it?
