Thanks for that. Much appreciated.

Can someone please help me with some algebra. I need to find the intersections of 2 functions so that I can find the volume using cylindrical shells and I have become pretty rusty when graphing the functions. When setting the functions equal to each other I get: 4x-x^2=3 Now I forget...

The first thing I did was sub the function into the derivative formula which made a huge mess of a problem to simplify. [(-1/sqrt2(x+deltax)) +2(x+deltax)] - [(-1/sqrt2x)+2x] all over deltax. I am a little rusty on working with radicals and tried a few things that ended up in a mess but I am...

Yes as delta x approaches zero. I know there is goig to be some conjugate or LCD stuff going on but i got stuck

ya but then how do you multiply out (x+deltax)^.5?

Please help me break down the first couple parts of this derivative question. This question gets a bit ugly: Find the derivative of F(x)=(-1/sqrt(2x)) +2x
