Answer 2

Formula and Rules of Trigonometry

$p = perpendicular \\ b = base \\ h = hypotenuse \\ pythagoras \: theorem \: = {h}^{2} + {p}^{2} + {b}^{2} \\ \\ \sin( \alpha ) = \frac{p}{h} \\ \cos( \alpha ) = \frac{b}{h} \\ \tan( \alpha ) = \frac{p}{b} \\ \cosec( \alpha ) = \frac{h}{b} \\ \sec( \alpha ) = \frac{h}{b} \\ \cot( \alpha ) = \frac{b}{p} \\ \\ \\ \sin( \alpha ) = \frac{1}{ \cosec( \alpha ) } \\ \cos( \alpha ) = \frac{1}{ \sec( \alpha ) } \\ \tan( \alpha ) = \frac{1}{ \cot( \alpha ) }$
