comment How do you calculate kw from kwh?
hmm, after 0.09 kw * h, it does a strange format automatically.

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'?

Sorry, Brian not sure I follow. "No" to what?

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?

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?

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.

Thanks Moron. Makes sense now. Funny name, but it doesn't match you.

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)?

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?

Thanks yunone. I don't think I would have spotted this on my own.

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?

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?

trutheality. Thanks. Makes sense now. Add a formal reply and I can accept your answer for points.

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....

comment Help seeing algebra in calculus
Doh! Thank you. I totally forgot about taking the derivatives of f(x)/g(x).
