=_=im stuck here..
OpenStudy (amistre64):
stuck on which part?
OpenStudy (anonymous):
x/9...
OpenStudy (amistre64):
if i asked you what the derivative of 5x was, what would you conclude?
OpenStudy (amistre64):
im assuming you know the power rule ....

Mmmm..i forgot..1/5x????????
OpenStudy (anonymous):
ohhhhhhhhh
Parth (parthkohli):
Well, \(\dfrac{x}{9}\) can be written as \(cx\). What is \(c\)?
OpenStudy (amistre64):
\[\frac{d}{dx}kx^n=kn~x^{n-1}\]
\[\frac{d}{dx}5x^1=5(1)~x^0=5\]
OpenStudy (amistre64):
\[\frac{d}{dx}\frac19x^1=?\]

Oh, \(c\) has been disclosed by Amistre. :-)
OpenStudy (amistre64):
<<<raises hand and waves it vigorously .... pick me pick me, i know what c is!!!
OpenStudy (anonymous):
c is 1/9;D
Parth (parthkohli):
Right there.
Parth (parthkohli):
I can do this without the power rule, just basic algebra. :-P

OpenStudy (amistre64):
so, what is the deriative of say:\[y=x^{2x}\]
Parth (parthkohli):
\[y = -\dfrac{1}{9}x + 1 \]As they say, the derivative is just the slope. What is the slope of this line I gave ya above?
Parth (parthkohli):
No, that one is Chain Rule. :-)

@-@IM sorrrrrry my internets working 2 bad!!!!ill @ u after 10minn
OpenStudy (anonymous):
Is it 1/9x?????????????????????????@p

sorry @ParthKohli
Parth (parthkohli):
Hmm, the slope of \(y = mx + b\) is only \(m\)

⊙△⊙?

oooohhhh goshhhhhhhhh finally got it!!!thanks soooo much~!>A<@ParthKohli
