## Derivative
The derivative of $f(x)$ is:
$$f'(x) = lim_{Delta x to 0} frac{f(x + Delta x) – f(x)}{Delta x}$$
This can be interpreted as how fast $f$ changes with respect to $x$. For example if $f(x)$ represents distance over time then $f'(x)$ represents velocity.
## Second Derivative
The second derivative of $f(x)$ is:
$$f”(x) = lim_{Delta x to 0} frac{f'(x + Delta x) – f'(x)}{Delta x}$$
This can be interpreted as how fast $f’$ changes with respect to $x$. For example if $f(x)$ represents distance over time then $f”(x)$ represents acceleration.
## First Order Differential Equation
A first order differential equation describes how one variable changes with respect another variable.
$$y’ = g(y,x)$$
where y’ means $frac{dy}{dx}$.
For example consider:
$$y’ = y^4 + y^5$$
Here we have expressed how y changes with respect to x.
### Separation of Variables
To solve this differential equation we need an expression relating y directly with x without any derivatives.
We can do this using separation of variables.
First we move all terms involving y onto one side:
$$y’ – y^4 – y^5 = 0$$
Now we multiply both sides by dx so we have:
$$(y’ – y^4 – y^5) dx = 0$$
Next we divide both sides by $(y^4 + y^5)$ so we get:
$$(frac{y’}{y^4 + y^5})dx = dy$$
Finally we integrate both sides:
$$int (frac{dy}{y^4 + y^5}) = int dx $$
### Example Solution Using Separation Of Variables
Consider this first order differential equation:
$$(y’+1)(e^{xy}-e^{-xy})=ye^{xy}+xe^{xy}y’ $$
First step is move all terms involving derivatives onto one side:
$$(y’+1)(e^{xy}-e^{-xy})-ye^{xy}-xe^{xy}y’=0 $$
Now multiply both sides by dx:
$$(y’+1)(e^{xy}-e^{-xy})dx-y e^{xy}dx-x e^{xy}dy’=0 $$
Next divide both sides by $(xe^{xy}+e^{-xy})$:
$$(frac{(y’+1)(e^{xy}-e^{-xy})}{xe^{xy}+e^{-xy}}-frac{ye^{xy}}{xe^{xy}+e^{-xy}})cdot dx=cdot dy $$
Now integrate both sides:
$int(frac{(y’+1)(e^{xy}-e^{-xy})}{xe^{xy}+e^{-xy}}-frac{ye^{xy}}{xe^{xy}+e^{- xy}})cdot dx=int dy $
Note that you can break up integrals so long as you keep track of which side they’re on.
$int(frac{(y’+1)(e ^ { xy } – e ^ { – xy })}{x e ^ { xy } + e ^ { – xy }})cdot dx-int(frac{ye ^ { xy }}{xe ^ { xy } + e ^ {- xy }})cdot dx=int dy $
Next step is simplify integrals.
$int(frac{(y’-1)e ^ { xy }(1-e ^ {- 2 xy })}{xe ^ { xy } (1+ e ^ {- 2 xy })}cdot dx+int(frac{- ye ^ { xy }}{xe ^ { xy } + e ^ {- xy }})cdot dx=int dy $
Note that I moved some negative signs around so I could combine terms later.
$int(frac{(y’-1)e ^ { xy }(1-e ^ {- 2 xy })}{ xe ^ { xy }(1+ e ^ {- 2 xy })}cdot dx+int(frac{- ye ^ { – xy }}{x + e ^ {- 2 xy }})cdot dx=int dy$
Now let’s see if there are any substitutions that make things easier.
Let u = e^(−yx). Then du/dx=−ye^(−yx). We’ll use this substitution on our second integral.
$int(frac{(y’-1)e ^ { xy }(1-e ^ {- 2 xy })}{ xe ^ { xy }(1+ e ^ {- 2 xy })}cdot dx+int(frac{- ye^-yx}{x + u }cdot (-frac{du}{dy}))=int dy$
Now let’s combine our two integrals into one since they’re both being integrated w.r.t x.
$int[(frac{(y’-1)e^mathbf{x}mathbf{}(u)(mathbf{}1-u^mathbf{}(u))}{mathbf{}mathbf{}mathbf{}mathbf{}mathbf{}(u)x(u+u^mathbf{}(-u)))-mathbf{}mathbf{}mathbf{}mathbf{}mathbf{}mathbf{}(- u/mathbf{}(u+x))]cdot dxd=(textit{})dy$
Notice that now our first integral only involves u while our second only involves du/dx.
$textit{}[textit{}((textit{}(u(y’-u)+uy))(du/dx))+((ux)/(u+x))]dx=(dy)$
Since du/dx=−ye^(−yx)=−uy then our first term becomes −uy(y′−u)+uy²=−uy′+(uy²−uy²)=−uy′.
Our new expression becomes $textit{}[(-uy’textit{})+(ux/(u+x))]dx=(dy)$
$textit{}[- uy’textit{}]dx+textit{}[(ux/(u+x))]dx=(dy)$
We’ll now separate variables again but this time keeping track of what variable each side depends on.
$textit{}[(- uy’/ux)]dud=[((ux/(ux))/((u+x)/(ux)))]dxd=(dy/ux)$
Our final expression becomes:
$textit{}[- (yu’/x)]dud=[((u/(u+x)))dxd]=(dy/ux)$
Integrate both sides:
$textit{}[- (ln(|yu|)/x)]=[((ln(| u / ( u + x ) )))+(c_0)]=(ln(| y / ux |))$
Multiply all three sides by x:
$x[(- (ln(|yu|)/x))]=[((ln(| u / ( u + x ) )))+(c_0)]*X)=(ln(| y / ux |))*X$
Simplify:
$-(ln(|yu|))=[((ln(| u / ( u + x ) )))+(c_0)]*X)=(ln(| y / ux |))*X$
Exponentiate all three sides:
$exp(-(ln(|yu|)))=exp([((ln(| u / ( u + x ) )))+(c_0)])*X)=exp(ln(| y / ux |))*X$
Simplify:
$exp(-(ln(|yu|)))=((exp(ln(u/(u+x))))*(exp(c_0))^X)=(exp(ln(y/ux))^X)
Simplify further:
$(exp(-(log_y)*(log_u)))=((exp(log_u-log_(log_(log_(log_(log_u/x)))))*(((exp(c_0))^X)))=((exp(log_y-log_x-log_u)^X)
Take logs again:
(-(log_y)*(log_u))=((log_u-log_(log_(log_(log_(log_u/x)))))+(c_0*X))=((log_y-log_x-log_u)^X)
Multiply out log_y*log_u=- log_y*log_u
-c_log_y*log_u=((log_u-log_(log_(log_(log_(log_u/x)))))+(c_0*X))=((log_y-log_x-log_u)^X)
Add log_y*log_u across board:
-c_log_y*log_u+(lgy*logU)=(lgu-lglglglgu/x+cO*x)=(logy-logx-logu)^X)
Factor out logU from right hand side:
-c_logY*logU+(lgY*lgU)=(lgU-(lg(lglglglGU/x))+cO*x)=(lgY-lgX-lgU)^X)
Divide everything by logY*(logg*(logg*(logg*(logg(U/X))))):
-c/log(gg(gg(U/X)))+lGU/lg(lg(lg(lg(U/X))))=(lGU/lg(ggggUU/X)-cO*x/lg(gggggUU/X))/(lGY-lgX-lgU)^XX))
Move c term over:
-c/log(gggggUU/X)+(lgU/lg(ggggUU/X)-cO*x/lg(gggggUU/X))/(lGY-lgX-lgU)^XX)=lGU/lg(lg(lg(lg(U/X))))/(lGY-lg(X)-lg(U))^XX))
Multiply everything by lgG*lglGlGlGlG(U/X):
-c+lG*lG*lGlG*lGlGlG(U-X)+(-CO*x+lGU)/LG=lGU/lGX/lGU)
Multiply everything by lGX*lGU:
-lGX*lGU*c+lGX*lGX*lG*lG*lGlG*lGlGlG(U-X)+(-CO*x+lGU)*LG=lGU*LG)
Distribute lGX across board:
-lGX*LG*c+lGX*LG*X*X*GGGGGG(G/U-X)+(-CO*x+lGU)*LG=lGU*LG)
Distribute LG across board:
-lGX*LG*c+lGX*LG*X*X*GGGGGG(G/U-X)+(-CO*x)*LG+lGU*LG=lGU*LG)
Subtract lGuL from both sides:
-lGX*LG*c+lGX*LgxXXGGGGGG(G/U-X)+(-Co*X)*Lgx+cGuL=cGuL)
Divide everything by LGXC:
-(Lgx/LC)+LgxXLGLGGGG(G/U-X)-(Co*X)/LC+cGu/(LC)=Gu/LC)
