When solving a first order differential equation

$\frac{dy}{dx}=f\left(y\right)$

for the fixed points (or steady states), we set the differential equation to 0 and solve for the values of y that are fixed points. Why does this guarantee that we will obtain fixed points? Why can't we obtain a point at which the slope is 0 but is not a fixed point?

Proving single solution to an initial value problem

$y\text{'}=\left|\frac{1}{1+{x}^{2}}+\mathrm{sin}|{x}^{2}+\mathrm{arctan}{y}^{2}|\right|,\left({x}_{0}\right)={y}_{0}$

or each $({x}_{0},{y}_{0})\in \mathbb{R}\times \mathbb{R}$ I need to prove that there is a single solution defined on $\mathbb{R}$

Getting into differential equations

I'm just getting into differential equations now and I've got to show that the given y(x) is a solution to the differential equation:

$${u}^{\prime}+u=0\text{},\text{}y(x)=C{e}^{-x}$$

How do I tackle this?

Given that f(z) is a strictly increasing function (with real input and output and no root) for which there exists some positive (real) value of b such that it asymptotically outgrows $z}^{b+1$ for positive z.

Is it true that any solution to

$\frac{dy}{dx}=f\left(y\right)$

will contain a vertical asymptote providing y (real) exceeds 0 at some point?

Conversely, is such a vertical asymptote impossible given that$z}^{b+1$ outgrows f(z)?

Solve the given differential equation by using an appropriate substitution.

(x-y)dx+ x dy=0

(x-y)dx+ x dy=0
