 Oct 30 comment How do you calculate kw from kwh? hmm, after 0.09 kw * h, it does a strange format automatically. Apr 4 comment Single Complement Variable + 1 Dilip, if I can specify whether x is complement or non-complement, then why do some laws specify X', such as DeMorgan's Law: X'Y' = X' + Y'? Apr 4 comment Single Complement Variable + 1 Sorry, Brian not sure I follow. "No" to what? Apr 4 comment Single Complement Variable + 1 Dilip, x + 1 = 1 for any x. But doesn't the x have to be non-complement? Or can x even be complements? May 5 comment Help on Inequality Proof Thanks makes perfect sense. Thank you. Mar 13 comment Finding limit of function with more than one variable: $\lim_{(x,y)\to(0,0)} \frac{xy}{\sqrt{x^2+y^2}}$ You're right. The author did use the squeeze theorem to prove that the limit existed. I was just wondering why he chose x=y^2 as one more test to see what the limit was. Why not x=y? or y=x? Feb 3 comment Understanding and Integrating/Differentiating Power Series Thanks Joe. Not notes, just me trying to understand what's going on in the problems. I was just wondering if my line of thinking was on the right path or if I was just completely out of line. When I first was introduced to this section, I didn't understand why we were integrating/differentiating functions and how they produced the power series we wanted. Feb 2 comment Integrating Power Series Thanks Moron. Makes sense now. Funny name, but it doesn't match you. Feb 2 comment Integrating Power Series What about plugging back in 1/2? If x = 1/2, then it's ln(1/2) = -ln2. What happened to the negative sign in front of ln2? It seems like they plugged it back into -ln(1-x) and not ln(1-x). If they did, why -ln(1-x)? Aren't we looking for ln(1-x)? Jan 17 comment How do you tell if a series is decreasing? Hm, I see that at x>e^1/3, the graph is below the x-axis. Ok, but how does solving for that show me that the equation is decreasing without looking at a graph? Jan 13 comment How far to go in a telescoping series Thanks yunone. I don't think I would have spotted this on my own. Jan 13 comment How far to go in a telescoping series hm, I just came upon a problem that doesn't involve fractions, but e. I guess it was pure coincidence. What determines, then, how far I must go? Jan 10 comment Finding the points of intersection in Polar Equations Andres, or to anyone else, I also have a question related to this problem. When I enter this equation into my ti-83, the leminiscate never completely closes its loop. Any suggestions how to do so? Jan 9 comment Finding the points of intersection in Polar Equations Thank you Andres. Dec 5 comment Ranges and the Fundamental Theorem of Calculus 1 Thanks Arturo! That was very thorough and informative. Dec 4 comment Calculate the surface area of a solid of revolution Thanks Arturo.. Nov 21 comment Hydrostatic Force and Integration trutheality. Thanks. Makes sense now. Add a formal reply and I can accept your answer for points. Nov 21 comment Hydrostatic Force and Integration Btw, the solutions manual solution to C is: Integral density*depth*2dx from 0 to 3. Which is Integral 62.5x * 2dx from 0 to 3. Why is the depth variable? I keep thinking "one end" means one side of the tank. Apparently, not.... Nov 15 comment Help seeing algebra in calculus Doh! Thank you. I totally forgot about taking the derivatives of f(x)/g(x).
