# Invertera matris 2x2

Inverse of a 2×2 Matrix. In this lesson, we are only going to deal with 2×2 square matrices.I have prepared five (5) worked examples to illustrate the procedure on how to solve or find the inverse matrix using the Formula Method.. Just to provide you with the general idea, two matrices are inverses of each other if their product is the identity matrix Anything larger than that, it becomes very unpleasant. So the inverse of a 2 by 2 matrix is going to be equal to 1 over the determinant of the matrix times the adjugate of the matrix, which sounds like a very fancy word. But we'll see for by a 2 by 2 matrix, it's not too involved. So first let's think about what the determinant of this matrix is Inom linjär algebra har en matris A egenskapen inverterbarhet eller invertibilitet, om och endast om det existerar en matris B sådan att = = där I är enhetsmatrisen.Då kallas A en inverterbar matris och B kallas inversen till A och skrivs A −1.Det följer av definitionen att både A och A −1 är kvadratiska matriser av samma dimension n×n.. Inversen finns hos kvadratiska matriser då bland annat matrisens determinant är skilt från noll. Bestämning av inverser till kvadratiska matriser är jobbigt, och härledningen är mysig - så den lämnar vi och visar bara helt enkelt hur man räknar ut inversen till en 2×2-matris
