What is the cardinality of the set A,B where My answer was 4 for set A and 6 for set B. When i looked at the text book for answer it is not provided in th...

I was wondering what exactly the term Fourier symbol, or sometimes said the symbol of the Fourier transform means. Also, are any books that cover this top...

In the study of elliptic curves, specifically in Weierstrass form, you have the equation $E : y^2 = x^3 +ax +b$. However I have found the discriminant com...

The piecewise function is $$f(x)=\begin{cases} ax^3 & x\leq 2 \\ x^2+b, & x>2 \end{cases} $$ First I plug in the 2 into both functions and set ...

I've been at this for a while... I tried to the inverse method but it keeps on saying I'm getting it wrong... Can anyone show me a step-by-step ...

I know that formula, but I don't understand it. $\log_a(b)=\frac{\ln(b)}{\ln(a)}$ Thanks.

Ok, so abelian groups are solvable. And Thm II.8.5 of Hungerford says A group is solvable iff it has a solvable series. (The group may be finite or infini...

How does one find out if a given number is a rational number or irrational number?

I am self-learning algebraic topology by reading Rotman's An Introduction to Algebraic Topology. I am stuck on Exercise 3.4 on page 41. I'd be g...

I was given that $$p(t)=(1+2\cos t)\mathbf i + 2(1+\sin t)\mathbf j + (9+4\cos t+8 \sin t)\mathbf k$$ and that I needed to find the tangent, normal, and b...
