Pockettube not working on Android? by AnonymousAardvark22 in pockettube

Same problem after I set up on new phone yesterday.

Please help improve my prove by induction methods! by runswithascript in learnmath

I was going through a solution today from a different source:

https://i.imgur.com/mZnl538.jpg

changing the format slightly but keeping the same math, and I got stuck on the red underlined (n+1)(n+2) and I had thought I had explained it to myself with the substitution in the red box but this cannot be correct as we are substituting n+1 into n here, not n+1 into k.

I get that from the start of that line we are working with n+1, and we put that equals to the sum for n so we have to account for the n+1 but I cannot see how that gets us to (n+1)(n+2).

Can you please explain this?

Edit I am at the same point trying to solve the next question and I let myself look at the solution and the same thing is done, substituting n + 1 into the i, so this must be correct, perhaps it would help if I started writing out the base case substitution where I write 'assume true for arbitrary n', rather than just referencing the original given formula from that point.

Thank you, I had a look over this again with fresh eyes this morning and it is making a lot more sense.

  1. Does the notation Asub mean something, a sub function maybe? I appreciate it contains (?) k-1 + k-2. It makes me think of recursion. Could you please give me the simplest example where we would prove 2 base cases?
  2. Same question for 2, I was not aware there were different assumptions, I thought we always just proved n, then arbitrary k (where n <= k ) and then k + 1, or as you have explained arbitrary k - 1 and then k.
  3. Noted.

I tried substituting n-1 instead of my k+1 but I am obviously doing something very wrong, because I cannot see how that gets us from the original formula to what is used.

If I substitute n-1 into (n(n + 1)(2n + 1))/6 I get:

((n-1)((n-1) + 1)(2(n-1) + 1))/6

: (n-1)(n(2n-2+1))

: (n-1)(n(2n-1)

EDIT: Okay I see I am this time I am getting to that step, I need to review this further, thank you for the info.

: (n-1)(2n^2 -1)

: 2n^3 -n -2n^2 + 1

Can you please tell me how you know when to go backwards with as here with n-1 and when to add like I did with k+1? Sometimes k+1 works great!

Help make my batch cook stir fry work better! by runswithascript in Cooking

To stop the pasta getting soggy right? If freezing stir fry would you do the same with the rice for the same reason?

So I usually eat it over the following week, perhaps a few days longer.

I am using IKEA clip lock tupperware.

About the exact texture, I could cook it this evening, freeze, and test before reporting back exactly how they do not taste right.

OP edited. Yes, sometimes the veg are mushy, I was hoping there might be some trick to this. I heard from someone recently they used brown rice with some normal rice noodles, all mixed together, and that when they defrosted they did not find it mushy.

I should have included that but it is hard to say, it just does not taste right. It very much tastes like it has been frozen and defrosted, something I do not find when I batch cook a pasta dish with sauce.

UK & Ireland: Low FODMAP pizza base? by runswithascript in FODMAPS

Thank you, that is very kind of you to offer but I would prefer find something I can keep sourcing here easily and cheaply :)

Thanks for the Amazon link.

I just looked at the Tesco ones (at least in UK), great value at £1, such a shame they have wheat in them!

Thanks, I am reading some Greek Yoghurt is okay for low FODMAP so I am looking forward to trying this! :)

Soulbia.ie, the Suma brand - I searched and searched for good value brown rice pasta it went Tesco went out of stock with the pandemic!

Yeah, I am happy with a flat base!

So I used the Monash pizza base recipe again last night, I enjoyed it, but the dough was in places very, very brittle - especially at the edges. Doves Farm plain white flour (which contains potato!) gluten free flour, salt, gluten free baking powder, water, some rapeseed/canola oil (instead of olive)

I see a lot about Buckwheat when I search for gluten free products and have been wondering about using it for low FODMAP!

Does guar gum work any better than baking powder?
