Question

यदि sin A = 1/2, a cot A = ?​

Answer 1

$\textbf{\underline {\underline {Solution :}}}$

$\sin \: a = \frac{perpendicular}{hypotanus} \\ \frac{p}{h} = \frac{1}{h}.$

$\textbf{:We Need to Find Hypotenuse for Further Step :-}$

${h}^{2} = {p}^{2} + {b}^{2} \\ {h}^{2} = {1}^{2} + {2}^{2} \\ h = \sqrt{3} \\ \cot(a) = \frac{b}{p} = \frac{2}{1} .$

: Hence The Cot A =2/1.
