right?
then wht

(sqrt(2) - y)(2 - sqrt(y)) = 2sqrt(2) - sqrt(2y) -2y +ysqrt(y).

And I don't think you can do anything more than that. To be honest, I think it's simpler in its factorised form.

i second that!

I guess you can also say:

2sqrt(2) - sqrt(2y) -2y +ysqrt(y) = 2^(3/2) - (2y)^(1/2) - 2y + y^(3/2)

if you wanted to completely work out the problem, then yes!
good work there, polylog!

Thanks
Although it's arguable which of these forms is "simplest"!
For taking a derivative or integral, the final form is certainly most conveniant.

holla · 2006-10-13 05:45:40

don't worry about it...
right, but this form seems to suit the equation just fine. is there even a simpler form using the methodology used to get to this somewhat-final answer anyway?

thank you very much everyone = )

holla · 2006-10-13 05:50:18

no worries!
