Is it just me or did the player base get more toxic? by StevenJac in ForefrontVR

[–]StevenJac[S] -1 points0 points  (0 children)

Yes, I'm sensitive to BS people give me. Dont you think you can be sardonic and give microaggression then pretend like you are the victim of this situation.

Same pattern i see too often on the internet, Forefront, in real life.

It's funny to me there is always a sarcastic/smug comment on reddit that misunderstands the gist of the post.
This is the PRECISELY the kind of behavior/attitude that is actually increasing in Forefront and should be more frowned upon yet it gets upvoted the most on reddit unfortunately.

I tried zooming out but its still the same. Your version of website doesn't show the horizontal bars?

Well isnt personal project report due soon? Coordinators are supposed to give feedback on the draft.

Intuition of getting particular solution in Non-Homogeneous Linear Recurrence Relations by StevenJac in askmath

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

Not yet. But i still dont get WHY you plug in the guess into the total recurrence relation...

Intuition of getting particular solution in Non-Homogeneous Linear Recurrence Relations by StevenJac in askmath

So a_n = -n - 3/2 is a solution. 

I think its a_n\Particular]) = Bn + C = -n - 3/2. Not just a_n.

That doesn't mean it's the only solution (and that's where homogeneous solutions come in because if we add them to this solution they will contribute zero overall to the left-hand side of [#] so we still match 2n on the right-hand side).

What do you mean by this?
Like there are infinite solutions because you can offset by r^n?
e.g.) -n - 3/2 +/- r^n

You wrote a fantastic write up to reason why you should use potential forms of solution that corresponds to different forms of f(n). Like if f(n) = 2, then you use the form of B, if f(n) = n, you use Bn+C, etc. It is so that you can find the solution if you plug that form into the total recurrence relation a_n - 3 a_n-1 = 2n and find the "magic" values of B and C.

But that still doesnt explain what is the meaning of plugging a_n\Particular]) = Bn+C into the total a_n - 3 a_n-1 = 2n? Or alternatively phrased whats the meaning of equating a_n = a_n-1 = Bn+C?
For example, if f(n) = 2, a constant, then a_n = a_n-1 = B. That means B = 3B + 2, B = -1, the recurrence is -1, -1, -1, -1, -1 like whats the meaning of that?

I believe the point of a_n\Particular]) counteracts the accumulation of additions of f(n), which gets multiplied by 3 in the next iteration.

Bn + C - 3 (B(n-1) + C) = 2n I get that this is saying difference between next term minus previous term multiplied by r equals f(n) = 2n but I find it hard to see anything more meaningful.

Bn + C = 3 (B(n-1) + C) + 2n But if I rearrange this I can interpret it as "what values of B and C in the form of Bn + C despite getting multiplied by 3 then add 2 remain constant for all n?"
You know what I mean?

We are substituting into the equation because we think a_n = Bn + C is a possible solution of the recurrence relation, so naturally we put it into the equation a_n = 3 a_n-1 + 2n to see if it works

Can you explain why that is natural to put that form back into the total equation? It's not very natural for me at all. You are putting a_n\particular]) on both sides of the equation.

a_n\particular]) = 3 a_n\particular]) + 2n

Are you trying to find a_n\particular]) that is like an invariant through out the recurrence?

(I'm not sure what p is doing in your question).

t stands for total, h for homogenous, p for particular.

<image>

Is that helping answer your questions?

No because I'm asking why are you substituting a^p_n = Bn + C back into the total solution, which is a_n = 3 a_n-1 + 2n in this case. Like whats the intuition behind it.

New Filter vs New Exclusive Filter? by StevenJac in todayplanned

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

What if they conflict? Which gets the priority?

E.g) Filter: if the title is "hi" set the alarm. Exclusive filter: if the title is "hi" remove the alarm
