Solving Equations with E and In x - MIT OpenCourseWare
ocw.mit.eduSolving Equations with e and ln x We know that the natural log function ln(x) is defined so that if ln(a) = b then eb = a. The common log function log(x) has the property that if log(c) = d then 10d = c. It’s possible to define a logarithmic function log b (x) for any positive base b so that log b (e) = f implies bf = e. In practice, we ...
