Question

Trigonometric all formulas..

Answer 1

$\sin( \alpha ) = \frac{1}{ \cosec( \alpha ) } \\ \\ \cos( \alpha ) = \frac{1}{ \sec( \alpha ) } \\ \\ \tan( \alpha ) = \frac{1}{ \cot( \alpha ) } \\ \\ \cot( \alpha ) = \frac{1}{tan (\alpha )} \\ \\ { \sin {}^{2} ( \alpha ) } + {cos}^{2} (\alpha ) = 1 \\ \\ \frac{sin \alpha }{cos \alpha } = tan \alpha \\ \\ \frac{cos \alpha }{sin \alpha } = cot \alpha \\ \\ sin \alpha = \frac{perpendicular}{hipotenous} \\ \\ cos \alpha = \frac{base}{hipotaneous} \\ \\ tan \alpha = \frac{perpendicular}{base}$
