Notations

Notations for derivatives:

$\frac{d}{d x} f (x) = \frac{d f}{d x} (x) = \frac{d f (x)}{d x} = f^{'} (x)$

Derivation of trigonometric functions

$\frac{d}{d x} \sin (x) = \cos (x)$

$\frac{d}{d x} \cos (x) = - \sin (x)$

$\frac{d}{d x} \sin (k x)$ $= k \cos (k x)$

$\frac{d}{d x} \cos (k x)$ $= - k \sin (k x)$

$\frac{d}{d x} \tan (x)$ $= \frac{d}{d x} \frac{\sin (x)}{\cos (x)}$ $= \frac{1}{\cos^{2} (x)}$

$\frac{d}{d x} \cot (x) = - \frac{1}{\sin^{2} (x)}$

$\frac{d}{d x} \arcsin (x) = \frac{1}{\sqrt{1 - x^{2}}}$

$\frac{d}{d x} \arccos (x) = - \frac{1}{\sqrt{1 - x^{2}}}$

$\frac{d}{d x} \arctan (x) = \frac{1}{1 + x^{2}}$

$\frac{d}{d x} arccot (x) = - \frac{1}{1 + x^{2}}$

Derivation rules in short

Factor rule: A constant factor is preserved when differentiate

$(a \cdot f)' = a \cdot f'$

Sum rule: When deriving a sum, the summands can be derived individually

$(f_{1} + f_{2})' = f_{1}' + f_{2}'$

Product rule: Rule for deriving products

$(u \cdot v)' = u' \cdot v + u \cdot v'$

Quotient rule: Rule for deriving quotients

${(\frac{u}{v})}^{'} = \frac{u^{'} \cdot v - u \cdot v^{'}}{v^{2}}$

Chain rule: Nested functions go into a product of the inner and outer derivatives when differentiated

$(f (g (x)))' = f' (g) \cdot g' (x)$
