 10 Confusion in fundamental theorem of calculus 8 If $\vec{\nabla} \cdot \vec{V} \neq 0$ at only one point, will this prevent us from saying that $\vec{V}=\vec{\nabla} \times \vec{U}$? 6 How much rigour is this proof of multivariable chain rule? 4 Can we allow $f$ to be undefined at finitely many points in $(a,b)$ when formulating $\int_a^b f(x)\ dx=F(b)-F(a)$, ($F$ is the antiderivative of $f$) 4 Why is it contradicting?
