Best ResponseYou've already chosen the best response.3why do you need to isolate x from there ?

Best ResponseYou've already chosen the best response.0Maybe it's just really late....but isn't that already "y"?

Best ResponseYou've already chosen the best response.0basically i need to turn it into a "x=" form instead of "y="

Best ResponseYou've already chosen the best response.0i 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="

Best ResponseYou've already chosen the best response.0Or do you have to do derivatives too?

Best ResponseYou've already chosen the best response.0I'm using integrals because I need to find the volume of a graph rotated around the y axis

Best ResponseYou've already chosen the best response.1why dont you just complete a square

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

Best ResponseYou've already chosen the best response.0It 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.

Best ResponseYou've already chosen the best response.3completing the square will do it., do you know how to ?

Best ResponseYou've already chosen the best response.0I 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

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

binarymimic

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

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

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

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