A capital W of a set of functions, testing whether they are linearly independent.
Also known as: Wronskian, Wronskian determinant, W of f and g
The Wronskian is a determinant built from a set of functions and their derivatives, and a non-zero value proves the functions are linearly independent. The converse does not hold in general, which is the trap: a zero Wronskian does not prove dependence unless the functions solve a common linear differential equation.
Denotes the determinant whose rows are a set of functions and their successive derivatives, used to test linear independence.

Proves independence when non-zero but does not prove dependence when zero, except for solutions of the same linear differential equation.
