Proud dane.

With a bachelor in Mechanical Engineering and an on-going master in Sustainable Energy Engineering at The Technical University of Denmark, I'm just a sheep like everyone else.

A history of mud and push-ups in the Danish army as lieutenant and platoon leader.

Developing the thermoelectric product of my dreams is... my dream. Let's see what it brings.

comment Differentiation, using d or delta
Is $\delta$ really never used in math as the derivative symbol? E.g. it is used as example for a functional derivative here: en.wikipedia.org/wiki/Functional_derivative

comment Finding $\frac{\partial}{\partial x}\left(x^2+y^2+z^2\right)^{-1}$
Start with $(x^2+y^2+z^2)^{-1}=\frac{1}{(x^2+y^2+z^2)}$. Then use the chain rule to take the derivative.

comment Can't do basic integral
Your addition "From comments" is missing a minus before the $c$ in the denominator. If you correct this, then you will see that it equals the last expression you have written. You can always simplify integral expressions before integration like this to avoid those troublesome combination rules.

You were right, I made a mistake with a minus. It is corrected now. And yes, this equals what you have above.

What power is reduced? As an example, $\int x^{3} dx=\frac{1}{4} x^4+k $. The power is raised not reduced

Move the exponent inside the parenthesis before integrating.
