Linked Questions

Sometimes, one needs to find all the solutions of three simultaneous nonlinear equations in three unknowns $$\begin{align*}f(x,y,z)&=0\\g(x,y,z)&=0\\h(x,y,z)&=0\end{align*}$$ within a ...

I have a function cxyz[s1, e1, s2, e2], and I want to find at least one set of {s1, e1, s2, e2} for which the function's output ...

I am trying to obtain a list of coordinates at which two spheres intersect. Take for example the spheres: sp1=Sphere[{0, 0, 0}, 1] and ...

I would like to find the intersection points of two surfaces which are constructed with ListPlot3D. The first list is ...

I would like to define a function $f(x,y)$, with the variables x and y linked by an equation implicitly, so $f(x,y)=f(x(y),y)=f(y)$. Eventually I would like to draw a graph with $f(x(y),y)$ being the ...

Suppose we have two equation $f(x,y,c)=0$ and $g(x,y,c)=0$ where $c$ is an unknown constant. I am trying to plot a graph for $x,y$. One way to do it is to solve one of the equations for $c$ then ...

Plot3D[{-5 - x - y, -Sqrt[8 x^2 + 8 y^2]}, {x, -5, 5}, {y, -5, 5}, Mesh -> None, BoxRatios -> {1, 1, 1}, PlotLegends -> "Expressions"]

I'm a newbie at Mathematica. I'm trying to build a line in three dimensions. The best I can do is to build two planes and get a line on the intersection of those planes, like this: ...

I'm trying to plot the intersections of four spheres. I've got the spheres plotted using: ...

I have a problem with one of my school project :( I need to add function: $\sin(x)\sin(y)$ to elliptic cylinder $\left(\frac x a\right)^2+ \left(\frac y b\right)^2 = 1$ After few hours, only this ...

I have a complex function F[x,y], and now I want to plot the contour F[x,y] = 0. What can I do in order to have the contour plot vs Re[x] and y (That is, I want to treat y a real variable and x a ...

I'm using ContourPlot to extract data points from a rather non-trivial curve in the $(x,y)$-plane. However, the points are spit out in the order of increasing $x$ ...

I have this code: ...

I should be able to get this from the answer here - but, with apologies, I'm afraid I can't figure it out. I have a sphere and a plane as follows: ...
