The infamous and very useful equation to move from contour integral to surface integral, also known as Stokes theorem.

The differential and integral of a function is a very useful topic for those doing calculus and mathematics. The derivative of a function is a measure of how the function is affected by changes in the independent variable. And the integral of a function is the sum of the values of the function multiplied by the function.

As we all know well, maths is fun - but that doesn't mean it's easy. Integration can get very tiring very quickly (especially when your university won't let you use a book of standard integrals), so sometimes you just need a reminder that you don't need to.
