LIST ALL THE ATTENDANCE QUESTIONS FOLLOWED (IF YOU KNOW THEM) BY THE ANSWERS

1. What does the SIR model stand for?

The SIR model stands for Susceptible, Infected and Recovered.

2. Why is this property not true for y'(t)=y(t)^2

It does not hold becasue of the exponent

3. a1:= 5th digit of ruid if 0 make it 1
	a2:= the first digit
	a3:= the second digit

solve by hand and by maple the diff eq
a1*y''(t)-a2*y'(t)+a3*y(t)=0, y(0)=0, y'(0)=0


y=0


4. Why is the property that if a(n) is a solution so is C*a(n) not valid for the NON-linear Recurrence
a(n)=a(n-1)^2

becasue the equation has factors that do not allow that property to hold. It is not a linear equation.
