In mathematics, the Wronskian of n differentiable functions is the determinant formed with the functions and their derivatives up to order n – 1. It was introduced in 1812 by the Polish mathematician Józef Wroński , and is used in the study of differential equations , where it can sometimes show the linear independence of a set of solutions.
Józef Maria Hoene-Wroński (Polish: [ˈjuzɛf ˈxɛnɛ ˈvrɔj̃skʲi]; French: Josef Hoëné-Wronski [ʒozɛf ɔɛne vʁɔ̃ski]; 23 August 1776 – 9 August 1853) was a Polish messianist philosopher, mathematician, physicist, inventor, lawyer, occultist [1] and economist.

The Old Cape Henry Light, completed in 1792, was the first federal construction project under the United States Constitution. The history of Virginia Beach, Virginia, goes back to the Native Americans who lived in the area for thousands of years before the English colonists landed at Cape Henry in April 1607 and established their first permanent settlement at Jamestown a few weeks later.
Does the Wronskian need to vanish at every point? f1 (x) = x, f2 (x) = x^2, are linearly independent. W (f1, f2) is 0 at x=0, but it doesn't matter, because we only need one point where W is non-zero. x=1, W=1 is non-zero, so the functions are linearly independent. The converse is not necessarily true: W=0 everywhere does not imply that the ...
