    High School Solving the Mystery of Square Root x Multiplied by 1/x

    Thank you! For some reason I couldn't think of the reason to make the statement true. Life saver!

    High School Solving the Mystery of Square Root x Multiplied by 1/x

    How is squareroot(x)*(1/x)= 1/square root x can somebody please explain this? I think I am having a brain lockup...

    Differentiating (v^3-2v*squareroot v): A Try

    Well, I meant that he didn't really give us clues as to have other ways of solving them, your were a great help. I still had to differentiate the final answer which you gave me, but I was able to do that no problem. Thank you anyways, again you did help me.

    Differentiating (v^3-2v*squareroot v): A Try

    How can I vote you to be a life saver? Thank you so much, for some reason my teacher told me I HAD to use the quotient rule and I guess that blocked me to thinking of other ways! Thank you so much, your a life saver!

    So, nobody has an idea?

    so if someone could show me? maybe a step by step...cause I have wasted a while on this one problem...

    Differentiating (v^3-2v*squareroot v): A Try

    I don't think so, I haven't tried that I know the answer...because it is...(2v-1)/squareroot2 But I don't know how to get to that, I've tried everything...that I know of...and I still can't get that answer...

    Differentiating (v^3-2v*squareroot v): A Try

    Well okay, I wanted to see if by understanding how to derive squareroot v, I could understand a much bigger problem. The actual problem that is connected is this y=(v^3 - 2v*square rootv)/ v and I have to differentiate it, I know I have to use the quotient rule and I have tired but the dang...

    Differentiating (v^3-2v*squareroot v): A Try

    Ah, see that's the thing how to you differentiate a square root? I have no idea?

    Differentiating (v^3-2v*squareroot v): A Try

    Homework Statement How would you differentiate, (v^3-2v*squareroot v)? Homework Equations The Attempt at a Solution would it look like...3v^2 - v^-1/2 ?

    I have problems with differentiating

    Yea I actually downloaded the PDF, just that I haven't come on these boards in a while and I kind of forget the coding...:redface:, but thanks for your help.

    I have problems with differentiating

    \frac{3}{2}x^{-3/2} Sorry I need to start using the Latex I know...

    I have problems with differentiating

    Oh sorry, yea it is...y = \frac{x^2 + 4x + 3}{\sqrt{x}}

    I have problems with differentiating

    Okay let me try it and I'll show my answer hopefully I'll get the right one, thanks guys. Okay for the second one I got H'(x)=3x^2 + 3 - 3x^-2 - 3x^-4...right? And for the first one I got 3/2x^1/2 + 2x^-1/2 - -3/2x^-3/2

    I have problems with differentiating

    Homework Statement Differentiate. y=x^2 + 4x +3/(square root x) and H(x)=(x+x^-1)^3 Homework Equations The Attempt at a Solution For the first one I got x^3/2 + 4x^1/2 + 3x^-1/2 But I don't know if that is correct or where to go from here? The second I really...
