Numerically evaluating $\iiint_{C} \frac{ {\rm d}x \, {\rm d}y \, {\rm d}z}{x^2 +y^2 + z^2}$

What's the intuition behind the Co-Area formula?

Double integral comes out different after changing $dx$ with $dy$.

Evaluating $I(z,s)=\int_0^1\int_0^1\left(1-\frac{(1-x)(1-y)}{(1-(1-z)x)(1-(1-z)y)}\right)^{s-2}\,\mathrm dx\mathrm dy$

How can I "see" that calculus works for multidimensional problems?

Equation of Partial derivatives

Multivariable Chain Rule Formula doesn't make sense to me

Why are these two double integrals different ? A question on Dirac delta distribution

Partial Differentiation using chain rule

Prove $ \lim_{h\rightarrow 0}\frac{1}{h}\int_a^x[f(t+h)-f(t)]\mathrm{d}t=f(x)-f(a). $
