Describe the bug
When you open theorem.js.org with a certain window size and resize it, the sphere and the tetrahedron get disproportionately scaled.

Equation system need improvement

TheoremJS has a browser-friendly dist but it'd be excellent if that dist was a UMD or an AMD, so that loaders like d3-require could consume it.

Given the rigger-based build system I'm not sure what the right path to this goal would be, because I've never used rigger and it's quite a bit different from something like rollup or browserify, which would make UMD builds rather straightforward.

Describe the bug
When using findRoot, it is impossible to find the root of a polynomial with more than 4 elements, so (ax^3 + bx^2 + cx + d).

To Reproduce
Steps to reproduce the behavior:

1. Use the function on a polynomial with more than 4 coefficients/numbers (t.polynomial(1, 6, -8, -6))

Expected behavior
The roots should be gotten.

Screenshots / Output
the output is simply undefined or an empty array

NodeJS (please complete the following information):

• OS: [e.g. macOS 10.14] Linux ( Ubuntu 20.04 )
• Node version [e.g. v8.11.3] Node 18
• Version [e.g. v1.0] latest (1.2.0)

Complex numbers
I think that your library needs to get a complex numbers.

Actions with complex numbers
You can implement these basic actions with complex numbers:

• Addition
• Subtraction
• Multiplication
• Division
• Raise to the power
• Root
• Some trigonometrical functions
