Graphing with Mathematica and Parameters

[Automaton2000]

Homework Statement

Second part of Part C is: Use mathematica to draw graphs for a few values of the parameters. [ Consider the cases b > 0 and b< 0]

Not sure how to graph with mathematica with parameters

You don't, that's why it says "for a few values of the parameters."

So you can use your favorite method to assign the parameters,
varying from the ugly

a = 1;
b = -1;
A = 6;
Plot[P[t], {t, .., ...}]

or the better

Block[
 {a = 1, b = -1, A = 6},
 Plot[P[t], {t, .., ...}]
]

to my preferred

Plot[P[t] /. {a -> 1, b -> -1, A -> 6}, {t, .., ...}]

Using something like

Plot[P[t] /. {a -> {1, 2, 3, 4}, b -> 1, A -> -2} // Evaluate, {t, 1, 
  6}]

you can even plot multiple ones in the same plot.
