Question

evaluate the given integral
3(e^x/4 + e^-x/4)dx

Answer 1

is it this integral??? \(\large \int3(e^{x/4} + e^{-x/4})dx \)

Answer 2

yes

Answer 3

u can break it into 2 terms and intergrate them seperately...

Answer 4

so it should look like \[3*e^{x/4} + 3*e^{-x/4}\]

Answer 5

do u howto integrate something with and e in it?

Answer 6

Are you sure it isn't \[
\int 3\left(\frac{e^x}{4}+\frac{e^{-x}}{4}\right)\;dx
\]

Answer 7

If it is indeed \[
\int 3(e^{x/4}+e^{-x/4})\;dx
\]Then first do a \(u=x/4\) sub.
