Joe, All built-in Mathematica functions and commands always begin with a capital letter. So you could use Log[2., 15] 3.90689 If you use an Integer as the first argument of Log you will obtain an exact answer and will then have to use N to obtain an approximate decimal answer. Log[2, 15] % // N Log[15]/Log[2] 3.90689 David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Joe [mailto:joealan at mac.com] To: mathgroup at smc.vnet.net Subject: [mg68216] [mg68176] Log Function I am very new so please be gentle. I am attempting to use Mathematica 5.2 for the first time and I am in trouble already. I want to take the log of 15. I have tried log[2., 15] and I get an echo. I tried N[log[2.,15]] I get a buzzer. What am I doing wrong? Thanks Joe
