 # Bernoulli's equation:
 ### $$\frac{ dy }{ dx } +P(x)y=Q(x)y^n \quad\quad n\in\mathbb{R},\quad n\ne0,1$$
->I'm calling this #de_b_type1. This is in standard form btw.
+>For now, I'll tag and refer to these as #de_bernoulli. This is in standard form btw.
 
 It looks almost like a linear equation! In fact if $n=0$ it is by definition. We will see further that if $n=1$ you get a separable equation. So we ignore the cases when $n=0,1$ as these can be solved with prior tools.
 
 Bernoulli's equations are important as you will see it in biology and in engineering.
-If $y$ is $+$ then $y(x)=0$ is a solution to the equation:
+Our goal is to find the general solution to $y$ which is some function of $x$. We should expect one arbitrary constant in our final answer for $y$ since this is a first order differential equation.
-$\frac{dy}{dx}+0=0\quad\Rightarrow \quad0=0$
+Notice there's an easy solution! $y(x)=0$ is a trivial solution to any Bernoulli equation.
+You can verify that by plugging in $y(x)=0$ to the original expression:
+$\frac{dy}{dx}+0=0\quad \implies \quad0=0$
+Now let's find the general solution.
 Let's move the y to the LHS:
 $y^{-n}\frac{ dy }{ dx }+P(x)y^{1-n}=Q(x)$
 notice that $y(x)=0$ is no longer a solution! It was lost due to dividing by zero. So from here on out we will have to remember to add it back in our final answers.
 let $y^{1-n}=u$
-Differentiating this with respect to x gives us:
+Differentiating this with respect to $x$ gives us:
 $(1-n)y^{-n}\frac{ dy }{ dx }=\frac{du}{dx}$
 $y^{-n}\frac{ dy }{ dx }=\frac{ du }{ dx }{\frac{1}{1-n}}$
 substituting in we get:
 $y^{-n}\frac{ dy }{ dx }+P(x)u=Q(x)=\frac{ du }{ dx }{\frac{1}{1-n}+P(x)u}$
 
-and we get a linear equation again: (Handy formula if you wanna solve Bernoulli equations quick. Just remember that once you find $u(x)$, substitute it back for $y(x)^{1-n}=u(x)$ to get your solution for y.)
+And that is a linear equation again, which can be solved with prior tools.
+Here's a handy formula if you wanna solve Bernoulli equations quick:
 $$\frac{1}{1-n}\frac{ du }{ dx }+P(x)u=Q(x)\quad \Box$$
+Just remember that once you find $u(x)$, substitute it back for $y(x)^{1-n}=u(x)$ to get your solution for y, and don't forget to add $y(x)=0$ with your final answer!
 >Remember when I said that when n=1 the equation becomes a separable equation?:
 >$y^{-n}\frac{ dy }{ dx }+P(x)y^{1-n}=Q(x)$
 >let $n=1$
 >$y^{-1}\frac{ dy }{ dx }+P(x)=Q(x)$

+For the final exam, I unfortunately couldn't find good study videos. I recommend studying PDE's hard, solidify your understanding of heat eq, driven heat eq, heat eq with non-zero end points, wave eq, and driven wave eq. Afterwards, I recommend studying power series since it's the next biggest scary monster. Finally, go over the rest of the past topics to fill your understanding and memory if you have the time. I'm thinking I should record a final exam review guide, hmmm. I'll update this text if I ever make one.

+Personally, I studied the material by attending the lectures and then reviewing/revising these typed notes at home, often relying on my prof's notes on eclass in case I copied off the whiteboard wrong/couldn't keep up. (eclass is the name of my university's online class management system.)
