Polynomial equations in one variable
These are standard formulas for the solutions of normalized quadratic and cubic equations.
Here are two simple equations of higher degree with solutions in terms of powers. They can be rewritten in terms of trigonometric
functions that sometimes automatically reduce to radicals.
Polynomial equations in more than one variable
Here we solve for
Clear the variable definition.
Here we solve two simultaneous algebraic equations.
Here are three simultaneous algebraic equations;

returns an empty list, indicating no solution. Every potential solution forces an equation in the parameter
alone, so there are no generic solutions.
We can get solutions by solving for

Equations involving trigonometric or hyperbolic functions, or their inverses
This is an example using the trigonometric function cosine.
