I have a table of integers, say A, and consider the counting function C, which, for a given x, gives the number of elements in A which are less or equal to x. Next, I want to plot C(x) in some range, ...

I am trying to find a neat way of applying an operation to each list element, but do not know how to properly use multiple slots or whether it is actually possible to solve this with multiple slots.
I ...

I have a list of lists -- a list of sublists -- that I wish to sort in a specified order. The following function, sortBy2ndElement, sorts a list of lists (...

Any suggestions as to how to speed up the computational time for this quantum walk problem which is coded using a normalized SparseArray coin operator as follows:
...

This is the bar chart. I need to remove the overextensions of the bar lines, reduce the space between consecutive A,B,C,D. However, I also want to retain/ add space between the three groups of ...

For my Calc III class, I need to find $T(t), N(t)$, and $B(t)$ for $t=1, 2$, and $-1$, given $r(t)=\{t,t^2,t^3\}$.
I've got Mathematica, but I've never used it before and I'm not sure how to coerce ...

I'm solving equations with many Cosines and Sines.
And I want to convert all the Sines to Cosines using trigonometric formulas such as cos(x)=sin(x+pi/2).
How can I do this?

I've seen questions before such as "What is the best open-source equivalent for Mathematica?", but that specific question (and that line of inquiry in general) cares more about the computer algebra ...

Here is a start. I'm looking for a nice way to draw it.

I quite often would like to draw graphics in my $\LaTeX$ documents using Mathematica. I have encountered three problems. I would like to know if there are any workarounds to these problems
I would ...

Here is a start.
MapIndexed[Text[Reverse[First[RealDigits[Pi,10,252]]][[Tr@#2]],#]&,
Table[{t Cos[t],t Sin[t]},{t,0,16Pi,0.2}]]//Graphics

At the moment I am trying to construct a bifurcation diagram of the iterative function $f(x)=$ $ax-1.1975x^3$. I've scoured the internet for pre-made bifurcation diagrams and found many (mostly of the ...

I have $x_i$ sampled IID from $\mathcal{D}$=Gaussian in $\mathbb{R}^d$ with 0 mean and diagonal covariance $H=\operatorname{diag}h$ and need to find the largest value of $\alpha$, such that the ...

I'm solving 2D poisson problem of a finite volume problem using TDMA.
The solution of the problem is given:
\[Phi][x_, y_] := x^2 y + x y^2 + 1
The definitions are ...

In my recent studies, I have come across a very strange anomaly with C compiled functions. When I call a function that has the 'Listable' attribute while global variables are accessed through ...
