Question

Integrate (e^t sinht) dt

Answer 1

maybe you can just remind me of sinht identity :))

Answer 2

sinht =(e^t-e^-t)/2
e^t sinht =e^t (e^t-e^-t)/2
=(e^2t-1)/2
Take integration for this

Answer 3

I got .25 (e^2t - 2t) + C

Answer 4

good

Answer 5

You can take this as a lesson or some important point:

In case of indefinite integrals involving e and sinh or cosh, expanding cosh and sinh in terms of e^? \(\pm\) e^? helps a lot.
