I'll leave you to put in the limits.
I'm in a bit of a rush, but have you tried integrating it using ?
Find the Length of The Curve
y = ln(1 - x2)
0 < x < (1/7)
I got the derivative: (-2x)/(1-x^2)
Then i put it in the formula : sqr*(1+((-2x)/(1-x^2))^2)
My problem seems to be simplifying the terms to cancel the sqr* before integrating.
Hello, NickytheNine!
It seems you need to brush up on your Algebra . . .
Find the length of the curve: .
I got the derivative: .
Then i put it in the formula: .
My problem seems to be simplifying the terms . . .
Under the radical, we have: .
. . . . .
Then: .
And we must integrate and evaluate: .

I recommend long division: .
Got it?
