I have heard all kinds of great things about Clifford/Geometric algebra, but I can't find any good resources. I have been looking EVERYWHERE for just...

I've seen the Sobolev space defined as: The Sobolev space $H^k(\Omega)$ is the set of all functions $u \in L_2(\Omega)$ for which the weak derivative...

I am given x1, y1, x2, y2 and θ. How can I find x3 and y3? By the way, there can be another line segment on the other side of AB (as if the line was rotat...

Like the title says, I'm trying to find $$\int_0^r x^2 e^{-x^2}\,dx$$ Where $r$ is some finite value. I've done one step using integration by pa...

The question is to find the work done in moving a particle in a force field: $$\overrightarrow F = 3x^2i+(2xy-y)j+3k$$ along the straight line from (0, 0,...

So I have the following integration: $\int{e^{-x}\sin{x}}$ I let u be the $e^{-x}$ and $dv = \sin{x} dx$ After doing the integration by parts I get:$(e^{-...

To define natural numbers one can either: use the Peano axioms in second-order logic; encode them in set theory as von Neumann ordinals. The relation betw...

I have been looking at the operations of a quadrotor drone. I am reading the maths behind it and in one section it mentions: "These equations of moti...

I am looking for a good online video resource to start studying Calculus. I am studying it alone, not part of any school or university. Trying to learn an...

What is $\longleftrightarrow$ used for in mathematics? I know about $\iff$ being used for "If and only if". Are they the same thing? I was watching a YouT...
