Question

Find the arc length of r(t)=<(e^t)(sint),(e^t)(cost),e^t> t is from 0 to ln2

Answer 1

I'm stuck with this step,

Answer 2

somehow I can't click on the equation button...

Answer 3

if anyone could provide a solution that would be nice!

Answer 4

no, L = ∫ || r'(t) || dt

Answer 6

put the f g and h functions in the square root... square each one and then simplify . after this take the antiderivative of the result and F(ln 2 ) - f(0)

Answer 7

I know the formula, it's just that the integration part troubles me because
im unsure of which methods of integration to use...
