Homework Help: calc bc (condensed

Posted by APpreciative student on Tuesday, September 14, 2010 at 10:25pm.

is the limit as x approaches 0 of sin3x over 3x equal to zero?
basically this is my problem:

lim [sin 3x / 4x)
x-> 0

~~~~I multiplied& eventually got to
.75* lim (sin 3x / 3x)
x-> 0

~so i figured since (lim (sinx/x)
x-> 0
was equal to zero, then

lim (sin3x/ 3x) also equaled 0
x-> 0

is that right? thank you !!!
(all of the x-> 0 should be under the "lim" -- just in case the text shifts...)
