Online Determinant Calculator Take the determinant of matrices with Wolfram|Alpha 1 2 3 3 2 1 2 1 3 Natural Language Math Input Vectors & Matrices More than just an online determinant calculator Wolfram|Alpha is the perfect resource to use for computing determinants of matrices. If the Wronskian is nonzero in some region, the functions are linearly independent. The det option specifies whether the determinant of the Wronskian matrix is also returned. W(y 1, y 2) = y 1 y 2 ' − y 2 y 1 ' The Wronskian is named after the Polish mathematician and philosopher Józef Hoene-Wronski (1776−1853).

Solving this ODE means ﬁnding a fundamental set of solutions so that ALL solutions are given by the general form. The Wronskian of two or more functions is what is known as a determinant, which is a special function used to compare mathematical objects and prove certain facts about them.
