## anonymous 5 years ago whats the integral of (e^x-2) dx?

1. anonymous

So what is the derivative of e^x-2? Just go backwards. What would you take the derivative to get e^x-2? Also, quick question. Do you mean e^(x-2) or e^(x) -2? Both are completely different.

2. anonymous

i meant e^(x) -2

3. anonymous

e^2x?

4. anonymous

what no

5. anonymous

nevermind is it, e^x -2x?

6. anonymous

So are you saying that the equation is $e^x -2x$ then?

7. anonymous

yeah

$\int {(e^x-2)dx}=e^x-2x+c$ where c is constant.

9. anonymous

that seems too simply...

10. anonymous

thanks for the help

Oh sorry, I misunderstood what you meant when you said "nevermind is it, e^x -2x?" I thought that was what you were taking the integral of.

12. anonymous

its fine, i worded it wrong so no worries

i've just spent an hour integrating using substitution so when i got an easy problem i got really confused...
