Just a question to clear things up regarding to the integrating factors for my exams tomorrow:
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...
