Except for Friday nights and possibly Saturdays. Is this true...

    Integration help

    \int \frac{e^{\sqrt{x}}}{\sqrt{x}} It's in the substitution rule/symmetric function section of my book, so I figure I probably have to use one of those techniques to solve it. I've tried doing a bunch of different u substitutions \sqrt{x}, e^{{\sqrt{x}}}, etc, but none of them seem right...

I get that they are opposites, but not why that should be the case... it's not at all intuitive. Is...
