Calculus 2: Introduction to differential equations

Name the order, linearity (linear or non-linear), and homogeneity (homogeneous or non-homogeneous) of the following differential equations.

Find the particular solution of the differential equation with initial condition y(e)=ey(e) = e.

Solve the differential equation: dydx=x+xy2\frac{dy}{dx} = x + x y^2 with the initial condition y(0)=1y(0) = -1.

For our first actual example, we're going to pretend this random differential equation with initial conditions that I just got from my textbook yields a solution that's very important to an engineer or scientist.

The question is: If we have a single positive charge in space, then the electric field at some point is inversely proportional to the distance from that charge squared. Now, if we double that distance from the origin on that same axis, what kind of behavior will we find for the electric field?

Calculate the derivative F'(x) of the function 4x3+2x+C4x^3 + 2x + C.
