Question

Find the length of the arc of the given curve y^3 = x^2 from (-1,1) to (8,4) @primeralph

Answer 1

I decided to solve for x. So I got x=y^(3/2).

Answer 2

Yeah, that could work......

Answer 3

and integrated from 1 to 4

Answer 4

so you're using dx/dy right?

Answer 5

yes.

Answer 6

answer?

Answer 7

3y^(1/2) / 2?

Answer 8

for the derivative of y^(3/2)

Answer 9

your final answer.

Answer 10

the integral from 1 to 4 of (1 + 9y/4)^(1/2)

Answer 11

Do you just need the answer or the whole process?

Answer 12

I get the process. I just wasnt sure if I was computing the antiderivative right because I keep getting the wrong answer.
