Question

I'm trying to use integrals to find the arc length of y=2x-5 in the interval [-1,3]

Answer 1

you are wanting to integrate along the arc, ir integrate with respect to "ds"
.

Answer 2

yes with respect to dx. I'm trying to use the arc length formula L= integral of (sqrt(1+(dy/dx)^2)dx)

Answer 3

because these are differentials, ds becomes:
\[\sqrt(dx^2 + dy^2)\]

Answer 4

oh, ok

Answer 5

you already know the formula

Answer 6

good

Answer 7

yes, Im just having a hell of a time using it lol

Answer 8

so first take the derivative of the equation
