WebAn inverse function essentially undoes the effects of the original function. If f(x) says to multiply by 2 and then add 1, then the inverse f(x) will say to subtract 1 and then divide by 2. If you want to think about this graphically, f(x) and its inverse function will be reflections across the line y = x. mddprov account has removed your workplaceWebIn geometry, a point reflection (point inversion, central inversion, or inversion through a point) is a type of isometry of Euclidean space.An object that is invariant under a point reflection is said to possess point symmetry; if it is invariant under point reflection through its center, it is said to possess central symmetry or to be centrally symmetric. mddprov account has been removedWebGeometric interpretations of matrix inverses.

Many difficult problems in geometry become much more tractable when an inversion is applied. … See more Inverse of a point To invert a number in arithmetic usually means to take its reciprocal.
