    Zumdahl's Chemistry

    Who said someone was going to copy? Was that the first thing that popped to your head? Sometimes, it happens that the teacher doesn't check each and every problem just see's that we did all of them. :rolleyes:

    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}...

    Dna and Protein?

    Dna is a double helix..made out of polynucleotides. Protiens are made up of amino acids(polymer).. DNA: the phosphate group bonds with the sugar covalently? and the bases have hydrogen bonds.. Protien consists of primary, second, tetiary and quaternary structures?

    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 = -------------------...
