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:
4. ### 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?

7. ### Symmetric Difference Qutotient

oh cool!!, so this is right?
8. ### Symmetric Difference Qutotient

One last question For what types of problems is the symmetric difference quotient useful?
9. ### 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}...

it is said that this can make an invalid approximation..any ideas?

what course is this ?
13. ### Dna and Protein?

oh yea...now i see the code word would be different which would change the base
