Homework Statement Evaluate lim h->0 ((8+h)^⅓ -2)/h. Homework Equations Hint: Let 8+h=x^3The Attempt at a Solution I've uploaded a picture of my calculation. But I am not sure if that is the final answer or is there a following step to get the answer.

I haven't but that makes sense. Thanks.

.

Thanks for correcting J_0 . Can you further explain this ∫2π0Jrdφ ??

Can you elaborate how can I use that equation?

Homework Statement (a)The current density across a cylindrical region of radius R varies according to the equation: J=J0(1-r/R), where r is the distance from the axis of the cylinder. The current density is the maximum J0 at the axis r=0 and decreases linearly to zero at the surface r=R...
