Oft musst du eine 2x2 Matrix invertieren, hast aber keine Lust erst das Gauß-Verfahren zu benutzen? Dann nutze einfach diesen Trick, der sich aus dem Adjunkt I've got a two-by-two matrix here let's say a is equal to a b c d so i'm going to keep it really general so this is really any two-by-two matrix and what i want to do is use our technique for finding an inverse of this matrix to essentially find a formula for the inverse of a 2x2 matrix so i want to essentially find a inverse and i want to do it just using a formula that it just applies to this matrix right here so how can i do that well we know a technique we just create an Augmented matrix Matrices. Find the Inverse. [ 1 2 3 5] [ 1 2 3 5] The inverse of a 2×2 2 × 2 matrix can be found using the formula 1 |A| [ d −b −c a] 1 | A | [ d - b - c a] where |A| | A | is the determinant of A A. Math Precalculus Matrices Practice finding the inverses of 2x2 matrices Practice finding the inverses of 2x2 matrices Practice: Find the inverse of a 2x2 matrix What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ. Ready-to-use formulas for the inverse of 2x2 and 3x3 matrices. For those people who need instant formulas!
