Question

Cot 30°/sec 30° + cosec 30°/tan 45°-2 cos o°/sin 30° +cos^2 45°

Answer 1

$\frac{ \cot(30) }{ \sec(30) } + \frac{ \csc(30) }{ \tan(45) } - \frac{2 \cos(0) }{ \sin(30) } + { \cos }^{2} 45 \\ \frac{ \sqrt{3} }{ \frac{2}{ \sqrt{3} } } + \frac{2}{1} - \frac{2}{ \frac{1}{2 } } + \frac{1}{2} \\ \frac{3}{2} + \frac{2}{1} - \frac{4}{1} + \frac{1}{2} \\ \frac{3 + 4 - 8 + 1}{2} \\ \frac{0}{2} \\ 0$
