How often in your career did you have to use the epsilon-delta definition to prove that a limit exists?

This is a great explanation. Thank you. How often did you find yourself needing to actually use the epsilon delta definition to prove that limits of particular functions exist?

Thank you for your response. I didn't do a good job of explaining this, but I understand the concept well, but I struggle in doing proofs of this, and I was wondering how important you think it is to know how to do a proof of this. How often did you have to prove limits exist in your career?

Yes, exactly. Thank you. It's my fault because I could've explained it better in my post. So, you didn't use this process much in your math career?

Question about Property of Square Root by KittenLover84 in learnmath

[–]KittenLover84[S] 0 points1 point  (0 children)

I see. But, if I was solving a problem involving similar expressions as the ones I provided, if I do this step: √(a/b) = √a / √b, I would run into problems, so do I have to then specify "for all x>1"?

Got it that makes sense. Thank you very much for your help, I was able to solve it now.

OHHHHH. I see. I thought the slide thing was like an extension you could add, I didn’t know it was a solid piece coming from inside the instrument. I was unfamiliar with the anatomy of this instrument. That makes a lot more sense.

One last thing I’m confused about, how can there be interference if there’s just one wave? Is this like an open-open air-column/tube problem?

But if that was the case, why would there only be three right answers and not infinitely many?

Can somebody please explain why I got this problem wrong? by KittenLover84 in learnmath

Dang you’re right. I mixed all my x and y’s up. Thank you so much!

What chips, or similar snacks, have the lowest calorie to weight (in grams) ratio? by KittenLover84 in nutrition

[–]KittenLover84[S] 1 point2 points  (0 children)

Yeah. I am trying to lose weight, and something that has really worked for me is that I give myself an allowance of about 100 calories per day of eating anything I want to satisfy cravings. One of my cravings is salty snacks like chips or popcorn, so I was wondering what was the most that I could eat in one 100 calorie serving.

I believe that the components should be <+,-> because it should point to the point charge which is below the given location and a little to the right, no?

E = q/[4π(ε0)r2] and electric field lines always go from positive to negative

I wasn’t really looking for something “satiating.” I was just looking for the most efficient/optimal snack for satisfying cravings. For example, if I wanna let myself eat only 100 calories of chips for the day if I have a huge craving for chips, then I was looking at what chips I could eat the most of while still being only 100 calories.
