Answer 1

HELLO DEAR,


$3( \frac{ \cos( 43) }{ \sin(47) } ) - \frac{ \cos(37) \cosec(53) }{ \tan(5) \times \tan(25) \times \tan(45) \tan(65) \tan(85) } - { \cos }^{2} 0 \\ = > 3( \frac{ \cos(90 - 47) }{ \sin(47) } ) - \frac{ \cos(90 - 53) cosec(53)}{ \tan(90 - 85) \times \tan(85) \times \tan(90 -65 ) \times \tan(65) \times \tan(45) } - {1}^{2} \\ = > 3( \frac{ \sin(47) }{ \sin(47) } ) - \frac{ \sin(53) \times \frac{1}{ \sin(53) } }{ \cot(85) \times \frac{1}{ \cot(85) } \times \cot(65) \times \frac{1}{ \cot(65) } \times 1 } - 1 \\ = > 3 - 1 - 1 = 1$
I HOPE ITS HELP YOU DEAR,
THANKS
