Question

How do you solve this integration?

Answer 1

\[\int\limits_{}^{} (Chx)^{2}dx\]

Answer 2

what is Ch

Answer 3

I wanted to apply the integration by parts which should be faster...

Answer 4

Chx is Hyperbolic cosine function

Answer 5

\[\int\limits_{}^{}(Chx)^{2}dx= \int\limits_{}^{} (Chx)(Chx)dx\]

Answer 6

I put then f(x)= Chx and g'(x)= Chx

Answer 7

\[\cosh x=\frac{ e ^{x}+e ^{-x} }{ 2 }\]

Answer 8

And the go on like this:
\[(Shx)(Chx)-\int\limits_{}^{}(Shx)^{2}dx\]
