Just a question to clear things up regarding to the integrating factors for my exams tomorrow:(adsbygoogle = window.adsbygoogle || []).push({});

The standard first order differential equation has the form:

dy/dx + p(x)*y = q(x).

where the integrating factor is e^(integral of p(x) dx).

But in one of the previous year paper, it has the equation

dy/dt + bt = a

where "b" and "a" are constants. To me, this does not resembles the standard form.

But apparently it is, in the answer they used the integral factor

e^(integral of b) and solved the equation.

I must have missed some important points in how to identify integrating factors...
