anonymous 5 years ago How do i evaluate the indefinite integral of: (e^-√x )/(4√x ) dx?

1. anonymous

Use a u substitution probably.

2. anonymous

for picking a u, I suggest $$u = -\sqrt{x}$$

3. myininaya

i agree with mr. polpak

4. anonymous

thanks, but i was wondering what would be considered the u part of the equation? The fraction is throwing me off

5. myininaya

polpak gave you u did you find the derivative of the u he gave you?

6. anonymous
