$

For example the first ODE is:

$\displaystyle

(x^2-x-2)\frac{dy}{dx}-y=0

$,

which may be rewritten:

$\displaystyle

\frac{1}{y}\ \frac{dy}{dx}=\frac{1}{x^2-x-2}

$

so the solution is:

$\displaystyle

\int \frac{1}{y}\ dy=\int \frac{1}{x^2-x-2}\ dx

$

2.How the example is rearranged into standard form

3.How to do the integrals?

Differencial is one of those words you always forget how to spell.
