Best ResponseYou've already chosen the best response.1g should be similar to the very first question. I'm going to predict that this is some sort of infinity.

Best ResponseYou've already chosen the best response.1It's hard for me to see i) so I'll hold my predictions.... :)

Best ResponseYou've already chosen the best response.0I got undefined after plugging in thr x value

Best ResponseYou've already chosen the best response.1OK, so if that's good enough for your teacher, then you are done. Otherwise you can try an x a little to the left and/or right as needed.

Best ResponseYou've already chosen the best response.1So there is a little  sign below the limit?

Best ResponseYou've already chosen the best response.1So you could try an x slightly to the left of 4 if you like.

Best ResponseYou've already chosen the best response.1Sure that should do it. A graph will also reveal which infinity this is.

Best ResponseYou've already chosen the best response.0I got 20 after plugging in 3.9

Best ResponseYou've already chosen the best response.0i want to try and do these without graphing, cuz were not supposed ot

Best ResponseYou've already chosen the best response.1Well, in that case... :)

Best ResponseYou've already chosen the best response.1Best answer at this point then since you got a negative, would be to say this is negative infinity.

Best ResponseYou've already chosen the best response.1Sure thing, let's see it!

Best ResponseYou've already chosen the best response.1I can make out everything except the x information under the limit.

Best ResponseYou've already chosen the best response.1Alright, so we obviously will get a 0 on the bottom, but let's look at the top, what is cos(0)?

Best ResponseYou've already chosen the best response.0i thoght x turn to 1 in hospitals

jtvatsim

Best ResponseYou've already chosen the best response.1Only if you get 0/0 as the limit when you first plug in. It's a key restriction.

Best ResponseYou've already chosen the best response.1L'Hospital only works when the limit is 0/0 exactly.

jtvatsim

Best ResponseYou've already chosen the best response.1In this case, we actually get 1/0. Since cos(0) = 1.

Best ResponseYou've already chosen the best response.0so what do we do from here?

jtvatsim

Best ResponseYou've already chosen the best response.1So this is yet another infinity it seems. :)

jtvatsim

Best ResponseYou've already chosen the best response.1That's true. But just like we were doing before, when you get undefined, it might be positive or negative infinity.

Best ResponseYou've already chosen the best response.0oh ok, and how would u find?

jtvatsim

Best ResponseYou've already chosen the best response.1Plug in x a little to the left. AND also an x a little to the right. We have to do both in this case because there isn't a left or right hand limit.

Best ResponseYou've already chosen the best response.1It's a two sided limit (no + or  subscript thing).

jtvatsim

Best ResponseYou've already chosen the best response.1Nevermind, that would be ridiculous.

Best ResponseYou've already chosen the best response.0wait, but the x is = 0

Best ResponseYou've already chosen the best response.1Anyways, maybe I should let you make the suggestions... zzzz

Best ResponseYou've already chosen the best response.1OK, you might want to get a little tighter than that, I'd say 0.1 and 0.1 just to be safe.

jtvatsim

Best ResponseYou've already chosen the best response.1You don't want the equation to think you are testing for x = 1 and x = 1... it has feelings too. :)

jtvatsim

Best ResponseYou've already chosen the best response.1Well, isn't that interesting? From the left, it looks like negative infinity. But from the right it looks like positive infinity.

Best ResponseYou've already chosen the best response.1The lefthand limit does not equal the righthand limit, this limit Does Not Exist!

jtvatsim

Best ResponseYou've already chosen the best response.1What's weird is that it isn't even Undefinied. It literally does not even exist! :)

Best ResponseYou've already chosen the best response.1Awesome. Glad to help! Good luck with your studies! :)

Best ResponseYou've already chosen the best response.0oh whats the difference?

jtvatsim
 one year ago
Best ResponseYou've already chosen the best response.1Undefined usually means it's some sort of infinity. It's just not a "normal" number.

jtvatsim

Best ResponseYou've already chosen the best response.1In this case, the right hand limit flies up to positive infinity, while the left hand limit flies down to negative infinity, leaving a huge break in the gap going in opposite directions.

jtvatsim

Best ResponseYou've already chosen the best response.1So, the (twosided) limit does not exist.
