Question

Evaluate the indefinite integral of e^4x

Answer 1

(1/4)e^(4x)<--- what would the derivative of this be?

Answer 2

@danielashvartz ?

Answer 3

\[\large \int e^{4x}dx\]
let u = 4x
so du = 4dx
so du/4 = dx

now substitute.. \[\implies \int e^u \frac{du}{4}\]
\[\implies \frac 14 \int e^u du\]
does that help?

Answer 4

I must have scared him away:P

Answer 5

\[\int e^{4x}=\frac {e^{4x}}4+c\]

Answer 6

...yes @UnkleRhaukus ....way to go....
