    Arc Length. Simplify expression

    Thanks for the quick reply but I'm not able to follow your work. sqrt (1/4e^2x + 1/4e^-2x + 1/2) = 1/2 (e^-x + e^x) I'm not sure how the above math is done. Thanks

    Arc Length. Simplify expression

    Homework Statement I'm trying to find Arc Length of F(x) = (e^x + e^-x)/2 0< x < 2]Homework Equations L = integrate sqrt ( 1 + (dy/dx))^2)The Attempt at a Solution (dy/dx)^2 + 1 = 1/4e^2x + 1/4e^-2x + 1/2] I don't know how to take the square root of the above function so I can be able...
