hi. i am trying to find the length of the curve
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
