Question

integrate the following function

Answer 1

\[\int\limits_{0}^{2}\sqrt{1+\cosh^2(x)}dx\]

Answer 2

this sounds fun

Answer 3

not so much

Answer 4

wolfram gives a scary answer

Answer 5

yeah i need steps

Answer 6

i have no clue sorry...if wolfram gives a frightening answer idk if i am able to solve it o.O

Answer 7

@Spacelimbus

Answer 8

although....if you wrote the question wrong it could be possible to solve..

Answer 9

nope ;that is right

Answer 10

I remember the elliptical integral function actually, but I doubt that this will help us anywhere here, I will have to take a look if some substitutions will work.

Answer 11

ok

Answer 12

Lets try it :D

Answer 13

Actually, you can't integrate it.

Answer 14

a series representation might work.

Answer 15

why?

Answer 16

Its an elliptic integral, just type it into wolfram. It doesn't have an antiderivative.

Answer 17

what about \[d/dx e^x-e ^{-x}\div 2\]

Answer 18

what you have makes no sense. You're integrating. Also:
\[\cosh(x)=\frac{e^x+e^{-x}}{2}\]
Not minus, thats sinh(x).
