When the electromotive force (emf) is removed from a circuit containing inductance and resistance but no capacitors, the rate of decrease of current is pr...

I want to find another graph that has 6 vertices and each has degree $3$ that is not isomorphic to these two graphs below. I know that these two graphs ar...

I know that the integral of $1/x^2$ is $(-1/x +C)$ Can we split $(1/x^2)$ as $(1/x)(1/x)$ and say that the integral of $(1/x^2)$ is $\ln x\cdot\ln x$? PS:...

I know which are the recurrent states {2,4,5} and It's clear to see it drawing a diagram but how can I prove that {2,4,5} are the recurrent states? I...

I can't seem to figure out how to set up this problem. I'm a bit confused on the relationship between the variables here; I've seen a simil...

$ i $ is the unit imaginary part of complex number , but there is a question which it is mixed me probably i missed the definition of a number , wolfram a...

I recently bumped into this theorem regarding the Laplace transform of periodic function: Given a periodic function $f(t)=f(t+p)$, where $p$ is its period...

What is the best way to see that the Ricci scalar curvature of $(S^n(r),g_{round})$ is a constant $n(n-1)/r^2$ ? I essentially only see this value stated ...

Does anyone know how to convert the equation of the line to the vector and symmetric forms: $x=-1-2t$ $y=1+3t$ $z=2+t$

I know the method. For a linear homogeneous ordinary differential equation with a root of the characteristic polynomial in $\alpha$ has multiplicity $k$, ...
