2.2 THE LIMIT OF A FUNCTION

Notes go here for 2.2... example:
$\lim _{z\to z_{0}}f(z)=f(z_{0})$

2.7 DERIVATIVES AND RATES OF CHANGE

To find the Tangent Line we use $\lim _{h\to 0}{\frac {f(x+h)-f(x)}{h}}$
We later apply the points on which we want to find the slope. </math>f(x)=x^2 f'(x)=\lim{h \to 0}\frac{f(x+h)-f(x)}{h}= \lim{h \to 0}\frac{(x+h)^2-x^2}{h}= \lim{h \to 0}\frac{x^2+2xh+h^2-x^2)}{h}=\lim{h \to 0}\frac{h^2+2xh}{h}=\lim{h \to 0} </math>

2.8 THE DERIVATIVE AS A FUNCTION

${\frac {d}{dx}}[c]=0$
${\frac {d}{dx}}[c\cdot f(x)]=c\cdot {\frac {d}{dx}}[f(x)]$

${\frac {d}{dx}}[f(x)\pm g(x)]={\frac {d}{dx}}[f(x)]\pm {\frac {d}{dx}}[g(x)]$
${\frac {d}{dx}}[x^{n}]=n\cdot x^{(n-1)}$
${\frac {d}{dx}}[a^{x}]=\ln(a)a^{x}$
${\frac {d}{dx}}[e^{x}]=e^{x}$
