Find the length of the following parametric curve.



$x  =  5  +  frac92 t^3$ , $y  =  4  +  3 t^frac92$ , $0 leq  t leq  2$.



I used integration and after some point I got lost :( Can anyone show me the steps?

    Is this $$x=5+frac92t^3,y=4+3t^9/2$$?

Apply the formula for arc length, we get
$$
int_0^2 frac27t^2,sqrtt^3+12 dt
$$
Then we make the change of variable $v=t^3+1$ to get
$$
int_1^9 frac 9 2 sqrtv dv = 78.
$$

      You must use the formula $$int_0^2sqrtleft(fracdxdtright)^2+left(fracdydtright)^2dt$$
      $$dx=frac923t^2dt$$ and $$dy=3cdot frac92t^7/2dt$$
