    Finding the Derivative.

    hello, i need some assistance on this problem: y = e^(1+lnx) 1st. I brought down the (1+lnx) by using natural log on both sides. lny*y'=(1+lnx)*lne y'/y=(1/x)*1 y'=e^(1+lnx)*(1/x) what do i do next?

    Symmetric Difference Qutotient

    now i see..i got the first part done.. \L\\\lim_{h\to\0}\frac{[a(x+h)^{2}+b(x+h)+c]-[a(x-h)^{2}+b(x-h)+c]}{2h} \L\\\lim_{h\to\0}\frac{ax^{2}+2axh+ah^{2}+bx+c-ax^{2}+2axh-ah^{2}-bx+bh-c}{2h} \L\\\lim_{h\to\0}\frac{4axh+2bh}{2h}...

    Symmetric Difference Qutotient

    Hurkyl, 1st thanks for replying, could you help me a little bit here...What's the 1st step i should do? (Prolly not finding the derivative of {symmetric quotient})..umm some help symmetric difference quotient: f(n + h) - f(n - h) ------------------- 2h

    Symmetric Difference Qutotient

    Show agrebraically that symmetric difference quotient produces the exact derivative f'(x) = 2ax+b for the quadractic function f(x) = ax^2+bx+c i know that: f(a + h) - f(a - h) Symmetric Difference Quotient = -------------------...
