This is an example of differential equation. a difference equation works as a formationlaw which prescribes how the \'next\' terms in the row emerged, once you know the\' previous\'.)

Given is:

question:

Solution

a^2 = a+1

it has two real solutions

a = -1/2 + sqrt(5)/2

and -1/2 - sqrt(5)/2

they will form two independent solutions

and so the basis
