Calculate the inverse of a 2x2 matrix using the determinant and adjugate formula.
All four cells must contain finite numbers. The determinant must be nonzero before an inverse can exist.
[[4, 7], [2, 6]] has determinant 10 and inverse [[0.6, -0.7], [-0.2, 0.4]].
The matrix is singular, so no inverse exists.
Yes. The calculator accepts finite decimal entries and formats the inverse to four places.
