Homework Statement
The website says this:
"It is Linear when the variable (and its derivatives) has no exponent or other function put on it.
So no y2, y3, √y, sin(y), ln(y) etc, just plain y (or whatever the variable is).
More formally a Linear Differential Equation is in the form:
dy/dx + P(x)y = Q(x)"
My question is whether what makes it a linear differential equation the fact that nothing on the other side of the equals sign from Q(x) has any degree higher than one or whether it is a linear differential equation because the differential doesn't have a degree higher than 1; for example, is this a linear differential equation?
dy/dx + y^3 = Q(x)
What about this one?
dy/dx + P(x)y = Q(x)^2

Note: Sorry on the title. I meant Linear Ordinary Differential Equation. Partial should not be in there.
