Personalized Actionable Insights
The determinant is 2.0000. The matrix is invertible (Det ≠ 0). Its inverse is [[1, -1.5], [-1, 2]].
Solve linear systems: For Ax = b, the solution is x = A⁻¹b. Multiply the inverse matrix by the constants vector to solve simultaneous equations.
Check linear independence: |Det| > 0 confirms the matrix rows/columns span 2D space independently. Use this to verify basis vectors.
Scale and transform: The absolute value of the determinant gives the scaling factor of the linear transformation — |Det| = 0.5 means the transformation halves the area.
Mathematical Formula & Equations
Understand the logic under the hood. Here is the formula and exact variable mappings utilized by the Matrix Calculator (2x2 Matrix) to compile results.
The Equation
Inverse = (1 / Det) * [[d, -b], [-c, a]]
Applies matrix algebra, evaluates trace metrics, and divides adjugate cells by determinant values to solve inverses.
