I can't seem to find out where to start or finish for this limit:
Lim 1-cos 3x / cos(squared) 3x - 1

Just factorise the bottom.
sorry, that would make it a lot easier, but the bottom 3x was suppose to be a 5x. Thats what makes it so complicated. NEED HELP
Lim 1-cos 3x / cos(squared) 5x - 1
The answer should be obvious from there.
that doesn't make it obvious. could you explain a little farther. Thanks
