kinda silly but
lim y=sin(x)
x> infinity
this would be 0 since that occurs most in a given period
and
lim y=cos(x)
x>inifity
is 1 because that occurs most ina period...
but what would be
limit y=tan(x)
x> infinity ???
would it be undefined because you can take each individual limit and get
1/0= undefined?

Best ResponseYou've already chosen the best response.0lim x>inf for all sinx cosx and tanx are undefined..

Best ResponseYou've already chosen the best response.0why you say it'll be 0 or 1 ? o.O

Best ResponseYou've already chosen the best response.0because thats what occurs most ina period... those are true fax

Best ResponseYou've already chosen the best response.0so you are saying that sin(infinity)= 0 ? would that mean, according to you, sin(infinity + pi/2) =1 ?

Best ResponseYou've already chosen the best response.0no shub because like with any limits if i had like 1/(x+1) the limit as x> infiity is not really impacted by the +1 so in ur example the pi/2 doenst really effect infiity

Best ResponseYou've already chosen the best response.1Look at a graph of sinx, cosx, or tanx, as x gets larger... what happens to the graph?

Best ResponseYou've already chosen the best response.1Or look at this animation of simple harmonic motion (makes a sinusoidal wave): http://upload.wikimedia.org/wikipedia/commons/7/74/Simple_harmonic_motion_animation.gif No matter how long you watch that, is the amplitude ever going to change?

Best ResponseYou've already chosen the best response.1There is no limit as x goes to infinity of sinx or cosx, this is a fact. They are constantly oscillating between 1 and 1, so you can't say for certain that it becomes anything at infinity.

Best ResponseYou've already chosen the best response.0its something like .. the limit doesnt exist... but it is assumed it would = 0 for sinx and assumed 1 on cosx

Best ResponseYou've already chosen the best response.0it was something like probability led the solution to kinda* exist

Best ResponseYou've already chosen the best response.1There's no guessing involved, as you increase to infinity sine and cosine functions do not converge towards anything. They will keep going between 1 and +1 forever.

Best ResponseYou've already chosen the best response.0thats true... but 0 occurs .... tbh i cant explain it like they did

Best ResponseYou've already chosen the best response.1The only time you might have a limit with sine or cosine converging towards something might be something like: \[\lim_{x \rightarrow \infty }\frac{ sinx }{ x }=0\]

Best ResponseYou've already chosen the best response.1^ it's probably something like what kainui posted. Damped oscillation.
