1. double integral HELP!!!

(5) / ( (25-x^(2)-y^(2))^(1/2)) dx dy

first integral dx goes from (25-y^(2))/2

second integral dy goes from 5 to zero

2. Re: double integral HELP!!!

Is the integral you're looking for this one?
$\displaystyle \int\frac{5dxdy}{\sqrt{25-(x^2+y^2)}}$

What about polar coordinates? (maybe after rescaling $\displaystyle x\to\tilde{x}=\frac{x}{5}$ and $\displaystyle y\to\tilde{y}=\frac{y}{5}$

3. Re: double integral HELP!!!

no x in numerator, unless book has misprint

4. Re: double integral HELP!!!

It may be better if you write the equations latex format or state what is the numerator and what the denominator, please

5. Re: double integral HELP!!!

where do i learn latex format?

6. Re: double integral HELP!!!

where are you coming up with math symbols for MHF?

This is called LaTeX (LaTeX - Wikipedia, the free encyclopedia) and will appear if you embrace latex code between "tex" tag. For instance

[ tex]\frac{a}{b}[ /tex]

will produce -removing blank spaces after [-

$\displaystyle \frac{a}{b}$

You've done exactly the same thing you did in the other post you did with the same question. You said where the x variables START, but NOT where they end. Until you tell us what both x terminals are, we can't help you much...

I think Einstein said it best - "Insanity is doing the same thing but expecting a different result".
