Roots of unity are the solutions of the complex polynomial $t^{n}-1=0$ they have the following form $E_{n}=\{e^{\frac{2\pi ik}{n}}:k\in\mathbb{Z}\}=\{e^{\...
I am asked to find the domain, co-domain, and to determine whether of not the transformation is linear. I'm not sure if I am doing this properly, so ...
Consider the vector field $F=<y,-x>$. Compute the line integral $$\int_CF\cdot dr$$ where $C$ is the circle of radius $3$ centered at the origin cou...
Having trouble with my homework. It goes like this: For each of G and H below, either give a planar embedding of the graph, or use Kuratowski’s Theorem to...
In the long exact sequence $\cdots \to \tilde{H} (A) \to \tilde{H}(X) \to H(X, A) \to \cdots$, why isn’t the third homology in the sequence given in a red...
I am working on problem #25 of Linear Algebra and its Applications and the question asks: Find an equation involving $g$, $h$, and $k$ that makes this aug...
What does it mean to say that a curve in $\mathbb{R}^2$ is embedded? I think a curve in $\mathbb{R}^3$ is embedded if it lies on a plane, but what does it...
I am thinking of passive transformations. I have read the idea that a translation rule can be expressed as a matrix by adding a new dimension. Can this di...
