Hi ppl. May I ask how you obtain the range of convergence for the maclaurin expansion of ln(1-x) and taylor's series, maclaurin's in general? Thanks, Joe

### Data

A power series is uniformly convergent everywhere inside its radius of convergence, so you just need to find that. The ratio and root tests are good bets.
