Here's the question you clicked on:
Ok, we don't care what actually happens at 2, just around. As we move closer to 2 on the left what are y values getting close to?
Right not what about from the right?
Is this correct then? http://gyazo.com/79e70a5b15e9035d7b632dc7793f31ab
you are right because left limit does not approach the same as right limit
The second question, it's does not exist, correct?
you are right because the left limit does not equal the right limit
Oh okay :-) Thank you. I'll be here for a while asking questions. Taking my calc midterm in 2 days.
left limit is infinity right limit is negative infinity they are clearly going in completely directions when getting closer to pi/2
different directions*
That's exactly what I thought. Thank you.
If we had |dw:1381514362557:dw| we could say the limit as x approaches 0 is infinity since both sides approach the same type of infinity
If we had this |dw:1381514417500:dw| we would say the limit as x approaches 0 doesn't exist because they approach different types of infinity
different types of infinity i mean positive and negative
