Best ResponseYou've already chosen the best response.0My work: y = x^3/2x + 1/2x ====> i split the fractions up dy/dx = x = 2/x^2 ====> this is where I messed up I think....

Best ResponseYou've already chosen the best response.0well the numerator is not in parenthesis, does that make a difference?

Best ResponseYou've already chosen the best response.0and even if you take a derivative for f(x) it wouldn't be 2x^31 right? it would be just 2x^3?

Best ResponseYou've already chosen the best response.0You need to use the equation editor if you don't know how to write properly!

Best ResponseYou've already chosen the best response.0A little! sorry about the little mess earlier lolllll dy/dx = x  1/2x^2

Best ResponseYou've already chosen the best response.1Yes you can, I still get popups. It just doesn't show up on the main list.

Best ResponseYou've already chosen the best response.1\[\large y=\frac{x^3+1}{2x}\qquad \rightarrow \qquad y=\frac{1}{2}x^2+\frac{1}{2}x^{2}\] \[\large y'=xx^{3}\]I think this is what you should be getting.

Best ResponseYou've already chosen the best response.1Remember, when you subtract one from a NEGATIVE number, it actually gets LARGER in the negative direction.

Best ResponseYou've already chosen the best response.1\[\large \left(x^{2}\right)\quad =\quad 2x^{21}\quad = \quad 2x^{3}\]Confused on this part?

Best ResponseYou've already chosen the best response.0I get how you got 1/2 x^2 but not 1/2 x^2 i split up the fractions to kinda help me see it :/ so I got \[\frac{ x ^{3} }{ 2x } + \frac{ 1 }{ 2x }\] which is \[\frac{ 1 }{ 2 } x ^{2} + \frac{ 1 }{ 2 }x? \] :( sorry lolll

Best ResponseYou've already chosen the best response.1Oh i wrote it wrong? :C woops...\[\large y=\frac{ 1 }{ 2 } x ^{2} + \frac{ 1 }{ 2 }x\] \[\large y'=xx^{2}\]
