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.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...\[\large y=\frac{ 1 }{ 2 } x ^{2} + \frac{ 1 }{ 2 }x\] \[\large y'=xx^{2}\]
