hi. i am trying to find the length of the curve(adsbygoogle = window.adsbygoogle || []).push({});

Find the length of the curve

x = (3) *y^(4/3) - (3/32)*y^(2/3) from -64<_y<_27

so i do the usual

calculate( 1 + (dx/dy)^2 ) ^(1/2)

then do the integral from -64 to 27 with respect to y

the only thing is i get an imaginary answer!!!

someone could please shed some light on this

thank you
