Maybe it's just really late....but isn't that already "y"?

...ok i meant in terms of x then whoops

Oh. Ha ha. Made me confused.

basically i need to turn it into a "x=" form instead of "y="

I actually need this for a calculus proble, but I'm having a brain fart.

OH..so ln and e^x and all that?

i need to find the radii of the "outer circle" and "inner circle" of the cross section that looks like a donut, so in order to express the radius in terms of the equation, i need it in terms of "x="

Or do you have to do derivatives too?

I'm using integrals because I need to find the volume of a graph rotated around the y axis

why dont you just complete a square

IsTimBest ResponseYou've already chosen the best response.0
Wait..does that diagram incldue x,y, z planes, or is that just 2D?
 one year ago

ctmusicgirl7Best ResponseYou've already chosen the best response.0
It should be 3D. Okay, the reason why I'm asking this "x isolation" question is because I need to find the volume of the graph of y = 4x  x^2 rotated around the yaxis and bounded by y=0.

completing the square will do it., do you know how to ?

That's the whole problem I'm working on right now.

I tried using the quadrative formula, but I got a numerical answer. Am I using it wrong? I'm having a big brain fart right now T_T

binarymimicBest ResponseYou've already chosen the best response.1
if you ever need to solve a quadratic just complete a square
 one year ago

binarymimicBest ResponseYou've already chosen the best response.1
in this case you need to solve for x, so complete a square to do it o_o

ctmusicgirl7Best ResponseYou've already chosen the best response.0
I'm not trying to solve it though. I need to have the x isolated :( Solvng it gives me a numerical answer.

I feel really stupid right now lol

Hey, don't say that, or I'll feel stupid for not remembering anything.

hartnnBest ResponseYou've already chosen the best response.3
let me give you first few steps.... y= 4xx^2 = (x^24x+44) y = (x2)^24 now can you isolate 'x' ?
 one year ago

binarymimicBest ResponseYou've already chosen the best response.1
they condition us to grow accustomed to f(x)! f(y) is just as important =[
