Question

solve tan(1/cosx)=sin(1/cos 1/2)​

Answer 1

Answer:

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