Question

cos (2pie+x)cosec(2pie-x) tan(pie/2-x) /sec(pie/2+x)cosxcot(pie+x)=1

Answer 1

Hey dear here is ur answer ******
___________________

$\cos(2\pi + x) \csc(2\pi - x) \tan(\pi \div 2 - x) \sec(\pi \div 2 + x \cos(x) \cot(\pi + x)$

=cos(90°×4+x)cosec(90°×4-x)tan(90°×1-x)sec(90°×1+x)cos x cot(90°×2+x)

=cos x(- cosec x) cot x(- cosec x )cos x cot x

=-cos x (1÷sin x) {-cot x(1÷sin x)}cos x cot x

=1 [proved]
