The question involves finding the arc length of the parametric equation x = e^t + e^-t and y = 5 - 2t
Arc length of a parametric equation ∫√(dy/dt)^2 + (dx/dt)^2 dt limits are from 0<t<3
The Attempt at a Solution
Taking the derivative of both x and y with respect to t and then plugging it later, I get
∫(2 + e^2t + e^-2t )^0.5 dt limits are from 0<t<3
Is this the right integral? If so, how do I compute it?
