solution or example that is ridiculously simple and of little interest.
Often, solutions or examples involving the number 0 are
considered trivial. Nonzero solutions or examples are considered
For example, the equation x + 5y = 0 has
the trivial solution x = 0, y = 0.
Nontrivial solutions include x = 5, y = –1 and x = –2, y = 0.4.
