Question

whats the integral of (e^x-2) dx?

Answer 1

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.

Answer 2

i meant e^(x) -2

Answer 3

e^2x?

Answer 4

what no

Answer 5

nevermind is it, e^x -2x?

Answer 6

So are you saying that the equation is
\[e^x -2x\]
then?

Answer 7

yeah

Answer 8

\[\int {(e^x-2)dx}=e^x-2x+c\]

where c is constant.

Answer 9

that seems too simply...

Answer 10

thanks for the help

Answer 11

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.

Answer 12

its fine, i worded it wrong so no worries

Answer 13

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