Can someone please confirm that this expression's limit DNE. I'm wasting too much paper to try and find out.
lim x-->0 (tan3x)/(tan5x)
Also does anyone have any tips on knowing where to stop for when a trig function has a limit that doesn't exist. I find that i'm just spinning my wheels on a lot of the questions that don't have limits.
Thanks!
Yes, thanks again. The answer came to me a few seconds after I hit the post button. Another question did come up. How did you simplify
limx-->0 (cos(5x)/cos(3x))
and am I correct in saying that it became the expression limx--> 3x/5x?
If so, how did it become that?
