Homework Statement
find the cumference of the loop 9x^2=4y^3 from (0,0) to (2/3, 1)
Homework Equations
length of curve square root (1+(dx/dy)^2)dy or square root ((dx/dt)^2 + (dy/dt)^2) dt
The Attempt at a Solution
i said x=9t/4 and y= (9t^(2/3))/4
then i found that 0≤t≤8/27
so after finding dy/dt and dx/dt i pluged that into that lengh of curve formula
the answer should be (4(square root 3))/3
But i m not getting the answer...
