There is a formula for arc length involving an integral that I don't want to type out. However, you do need to find the derivative of f, which in this case is just x. Then plug into your formula for arc length and chug it through the integral. Fan me if this helps. Thanks :p

i have the formula but i had trouble solving it

oh ok to solve whats in the integral, you need to use trig substitutions. Did you learn trig substitutions in class? So in this case, I would substitute x=secθ

i have to find the derivative first, not the integral
anonymous
  • anonymous
Yeah the derivative is x like i said before
anonymous
  • anonymous
isn't it x/4

Bring down the power, which is 2, and that cancels out with the 2 as the denominator. So you are left with x

this what i did x^2/2--> 2^-1x^2--->4^-1X
anonymous
  • anonymous
2^-1x^2--->4^-1X this is an error. Because 2^-1(2^1)=2

Ooops I mean 1

not 2

When you multiply two numbers with same base, then you add the exponent
