Question

यदि cos θ = m/n है, तो cot θ तथा cosec θ के मान ज्ञात कीजिए।

Answer 1

Answer:

$\cot( x ) = \frac{cos x}{ \sin( x ) } \\ \cosec( x ) = \frac{1}{ \sin( x ) }$

$\ {cos}^{2} x + { \sin }^{2} x = 1 \\ sinx = \sqrt{1 - {cos}^{2} x} \\ sinx = \sqrt{1 - \frac{ {m}^{2} } {{n}^{2} }} \\ sinx = \sqrt{ \frac{ {n}^{2} - {m}^{2} } {{n}^{2} {} } } \\ cosecx = \frac{1} {\sqrt{ \frac{ {n}^{2} - {m}^{2} } {{n}^{2} {} } }}\\ \\ cotx = \frac{m/n}{ \sqrt{ \frac{ {n}^{2} - {m}^{2} } {{n}^{2} {} } } }$

इसमे x की जगह पर $\theta$ लिख दो
