    Intergration problem

    Ey all, just wondering if anyone could help me do this :

    Intgrate: sqrt(1+(sinh(x)^2-1/4(sinh(x))^2)

    apologies for not using the correct function symbols, haven't yet worked out how to.

    Factor your sinh(x) and use the fact that cosh^2(x)=1+sinh^2(x).

    If you do it correct, you will have sqrt(3)/2 times the integral of cosh(x)
