Why doesn't Desmos Graphing Calculator graph $(-1)^x$?
Shouldn't it at least plot down $(-1)^0$ and $(-1)^1$?

How can you make a decimal point for a number display on Desmos?
I have this Desmos graph which is a number display. You type a button and that number gets displayed. I'm thinking about turning it into a calculator, but first I need a decimal point. (Also the negative function doesn't work, but that's a problem…

Why does Desmos not render graphs like this properly?
I was trying to show some students the graph of $y=4- \ln (2-x)$ today on Desmos.
Unfortunately we can see from the picture below that the graph does not render correctly around the asymptote and appears to 'stop' at around $y=40$. This same…

three-dimensional pixel
If we have some function, for example, $$y = ix^2$$, we can express that, (or any) function ($x,y$) with some kind of three-dimensional pixel ($t$ represents the pixel base whose length can be changed, and the values of $i$ can also be changed, in…

How can I plot a line vector in desmos?
If I go to desmos calculator and type for example 5cos(45),5sin(45) a point appears at 3.5, 3.5. I want this to be a line starting from the origin 0,0 but cannot see how to do so.
I see some point options when clicking the large dot to the left of…

How to make a collision system for a list of points and polygons in desmos?
So, I'm trying to make a basic shooter game in desmos, and I have a list of points that act as bullets. The (current) enemies right now are only some triangular jets that fly in a linear manner. My current goal is:
Make it so when the point hits…

How can i make Desmos equations only visible, if a variable is less than 0?
Say i have some variable k that I can change, and an equation. How do I make the equation invisible, if, for example, k<0 is true?
I tried to append {k<0} to the equation, which just made the equation invisible at all values of k.

Skew with Sgn(x) yields unwanted signed line segments
I'm using Desmos to visualize a concept, but I'm not getting what I expect.
Assume we start with a morphed circle, in green, focusing only on the positive y values.
We want to skew the green equal to its height (i.e. purple), from the center. To…

How can I create constants in Desmos which users cannot change with a slider?
I want to define a constant to use in a Desmos graph, but when I try to do this by creating an expression, Desmos allows users to change the value of that constant with a handy slider, e.g.,
Desmos suggested doing that by using a ratio of inbuilt…
