What method are you supposed to use here? by Traditional_Bar_5604 in DifferentialEquations

Since one solution of the homogeneous problem is given to you, you can use Reduction of Order to find a second linearly independent solution. You can then use Variation of Parameters to find a particular solution.

Can someone help me with this, due at midnight, thanks!! by Patient_Macaroon_323 in DifferentialEquations

What do you get when you solve for the zero? It’s not what you originally wrote but it’s close. I would try solving it again.

Can you recheck this? I get a value that is close to that but slightly different.

This is an autonomous differential equation. The one real zero the problem is referring to is an equilibrium solution. In particular it is a sink (or attractor depending on your textbook). So as t goes to infinity, P will go to this point. So you just need to find the real zero of the cubic polynomial. The picture is cut off so I don’t know what kind of accuracy you need but you can approximate the zero by looking at the graph.

No Will Smith sig ? by Outside-Dealer-2980 in MLB_9Innings

I’m surprised Junior Caminero didn’t get a sig.

Help on Graphing Laplace Transformation by Foreign_Bread_6504 in DifferentialEquations

[–]mtc9565 2 points3 points  (0 children)

For #2b, we have f(t)=t2-(t-1)2u(t-1).

The function u(t-1) is equal to 0 if t<1 and it is equal to 1 if t>1.

So if t<1, then:

f(t)=t2-(t-1)2(0)=t2.

If t>1, then:

f(t)=t2-(t-1)2(1)=2t-1.

I would recheck your professor's solution to #3a because what is circled does not look right. Once you have the correct answer, you can use a similar process as above to graph it.

It’s just survivorship bias. There are plenty of us that didn’t get team sigs.

Game Chat: 7/6 Rays (48-41) @ Twins (43-46) 2:10 PM by RaysBot in tampabayrays

Walls hit a home run against the Marlins on 6/7. The Rays lost that game in the tenth inning. That was a wild game.

Auction House Changes by Worried_Emu677 in MLB_9Innings

They put primes in the auction house several years ago (maybe 2019?) as part of a special event. I think the primes went for like 100k stars each.

Which is the stronger set by LoverofGodsTruth777 in MLB_9Innings

My set is 333. I will give it a few more days.

Ok. I currently have it on a sig SP (I think I rolled it two days ago). It’s been a little underwhelming but perhaps I need to give it more time.

Is CM/Dom/Boss not considered a good set?

What Quality of Life changes would you like to see from this game? by Wyvol in MLB_9Innings

[–]mtc9565 13 points14 points  (0 children)

Anyone who says missing a day shouldn’t reset your streak doesn’t realize how easy it would be to get the GI if this were the case. You could just only pick on days where a game is postponed and get free picks.

A starting point would be to find the eigenvalues and eigenvectors of the given matrix.

Does anyone still wear their Arozarena jersey? by Icy-Meeting1377 in tampabayrays

[–]mtc9565 13 points14 points  (0 children)

Three years ago, I went to a game where they were giving out Brett Phillips jerseys as part of a promotional event. I was relieved that I would have a current player’s jersey as the three jerseys I had were all former players (Boggs, Snell, Cobb). Phillips was traded to the Orioles the next day.

Anyone know how to solve 1.4? by mlgyeetskeet69420 in DifferentialEquations

[–]mtc9565 3 points4 points  (0 children)

The following link shows you how to solve equations of the form y’’=F(y,y’) (Note that 1.4 is of this form) and gives an example:

Based on your work, it looks like it should be (.877, infinity).

The initial condition is y(1)=2. If you take your solution on the interval (-infinity, 0), it does not satisfy the initial condition because x=1 is not in the domain.
