## How to report solution of ODE without im...

Maple 2020

I found an assignment question concerning an ODE from 20 years ago. This was before I had discovered Maple.

So I put it through Maple and got a complex solution, But the lecturer's solution was non-imaginary.

For a) gamma <> Beta and b) gamma = beta.

Actually for b) I couldn't follow his solution

This is a simple model of the covid infection as it applies here, down under, without the use of any de's like

I'm told a substantial number of people do recover within 45 days ....
So on the 45th day 1 person has recovered, on day 50 two people have recovered and so on.

Just want to know how to write this sequence...

## How to order a list of records ...

Maple 2019

Hello. Here is my question.

 >

#GIVEN:

ST := [`162` = Record(mu = 475, sigma = 41), `70` = Record(mu = 480, sigma = 42),
`168` = Record(mu = 448, sigma = 103)]

 (1)

Games:=[[`162`, `70`], [`70`, `168`], [`168`, `162`]]

 (2)

#I need Maple commands to follow the order of Games to auto create STO please

STO:=[`162` = Record(mu = 475, sigma = 41),`70` = Record(mu = 480, sigma = 42),
`70` = Record(mu = 480, sigma = 42),`168` = Record(mu = 448, sigma = 103),
`168` = Record(mu = 448, sigma = 103),`162` = Record(mu = 475, sigma = 41)]
