 Oct8 comment Finding $\lim\limits_{x\rightarrow 2} \dfrac{x^3-8}{x^2-x-2}$ Oh okay. That's sensible. Oct8 comment Finding $\lim\limits_{x\rightarrow 2} \dfrac{x^3-8}{x^2-x-2}$ And theres my answer.. I didn't even think that the denominator was factorable! How could I have missed that. Thank you - I will approve your answer when the time limit for which I can't approve any answer is up. Sep30 comment Question Regarding Limits and Confusing Notation @Henning: I'm mostly of English decent, but not from the UK - I apologize for the confusion though. Thank you so much for your time and help. Sep30 comment Question Regarding Limits and Confusing Notation I am a freshman at a university in the United States - this is my first semester, 5th week. Regarding my most previous comment @Henning, am I correct? Sep30 comment Question Regarding Limits and Confusing Notation @Henning The question mentions 'show that there is interval... blah blah blah... where f has the same sign as f(c)', so I have a feeling the answer to that question is 'No'. Sep30 comment Question Regarding Limits and Confusing Notation Actually, the professor didn't design the homework. We covered a section on continuity in the textbook, and he likes to skip parts of each section (obviously the part we've been talking about). The textbook company (I believe Pearson?) has an online homework system established for each section that my professor requires us to do. The educational level - well, this is Calculus 1. Sep30 comment Question Regarding Limits and Confusing Notation There's one more question this follows this, a simple yes or no: If the distance traveled away from f(c) is less than the absolute value of f(c), is it possible for f to change sign? Sep30 comment Question Regarding Limits and Confusing Notation @mixedmath: I'd rather not mention it, as not to really trash it's reputation. It's really got a great Computer Science program (and is #1 in its region) [which is my major], but the math department seems lacking. Sep30 comment Question Regarding Limits and Confusing Notation Upon reading this, it seems to me that the solution to my question would then be $\epsilon$ = $|f(c)|$. Sep30 comment Question Regarding Limits and Confusing Notation Would you mind elaborating on what the terms $\delta$ and $\epsilon$ even mean? My professor told us "not to worry about those", and the textbook doesn't define them. Some university... Sep30 comment Question Regarding Limits and Confusing Notation Well, another problem I have is that I have no knowledge of what $\delta$ or $\epsilon$ are/means. We were never taught about that matter, and we were even told "not to worry about it." Would you mind elaborating on these terms a little bit? Sep28 comment Why Does The Sine Expression Equal Another? That's exactly what I was supposed to do. Thank you. Sep28 comment Why Does The Sine Expression Equal Another? Oh, I see it now! Thank you very much. Sep27 comment Why Does The Sine Expression Equal Another? I was told simplify $\frac{\sin(\theta)}{\sin(5\theta)}$ by multiplying it by $\frac{5\theta}{5\theta}$. What I didn't get it how it yielded that solution. Sep27 comment Why Does The Sine Expression Equal Another? I still don't see where that $\frac{1}{5}$ comes from. Sep24 comment Finding Speed at a Single Point Is there any way to get an exact speed, and then round it? So far this is good though. Sep21 comment Re-writing a logarithm to a power So is that already in simplest form? (Also, would you mind checking the edit I added to the bottom, just to ensure that I'm doing this right. I'm attempting to remember how to use logorithms at this point, so I'm still a beginner). Sep14 comment Finding a side given 2 angles and a side (and rationalizing a denominator afterwards) Well, I did at first, but you saying that ensures me that I must have it right! Thank you very much for your help :). Sep14 comment Finding a side given 2 angles and a side (and rationalizing a denominator afterwards) Well I appreciate your help 168335 :). However, I've arrived at a rationalizing dillema now. Sep14 comment Finding a side given 2 angles and a side (and rationalizing a denominator afterwards) Thank you guys for that part! Now I having trouble rationalizing the denominator.. any help? (I editted the question to show this).
