WebAn invertible function is one for which we can find an inverse function. Recall that a function maps its input to a unique value. For example x^2 maps 3 to 9. And only to 9. … Webthat a square matrix A is invertible if and only if det A 6=0. Moreover, determinants are used to give a formula for A−1 which, in turn, yields a formula (called Cramer’s rule) for … formula ford lincoln pickering

Webgocphim.net WebMay 7, 2015 · The matrix is invertible if one of a, b, c are zero, but the other two aren't zero and aren't equal (thanks copper.hat for this correction). So the condition that a, b, c ≠ 0 is not necessary. However, your other 3 conditions are necessary. See the answers below for details. – JimmyK4542 May 7, 2015 at 1:06 4 Look up Vandermonde matrix.
