Geometrically an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction that is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed.
The Natural Log. The inverse of the function e x is the natural log function ln(x) . These two graphs are pictured below: Figure %: e x and ln(x) are inverses. Recall that if log a b = x, then x is the power that a must be raised to in order to equal b.With the natural log, the base is e. So, for example, ln(e) = 1.he Natural Log. The inverse of the function e x is the natural log function ln(x) . These two graphs are pictured below: Figure %: e x and ln(x) are inverses. Recall that if log a b = x, then x is the power that a must be raised to in order to equal b.
