Can anyone solve this....or tell me the process only how to solve this type of problems.....pls...​

Answer»

\frac{cos {30}^{0} }{sec {30}^{0} } + \frac{cosec {30}^{0} }{tan {45}^{0} } - \frac{2cos {0}^{0} }{sin {30}^{0} } + {cos}^{2} {45}^{0}

\implies\frac{ \sqrt{3} }{ \frac{2}{ \sqrt{3} } } + \frac{2}{1} - \frac{2 \times 1}{ \frac{1}{2} } + ( { \frac{1}{ \sqrt{2} } })^{2} \\ \implies \sqrt{3} \times \frac{ \sqrt{3} }{2} + \frac{2}{1} - 2 \times \frac{2}{1} + \frac{1}{2} \\ \implies \frac{3}{2 } + \frac{2 - 2}{1} - \frac{4}{1} + \frac{1}{2} \\ \implies \frac{3}{2} + \frac{0}{1} - \frac{8 + 1}{2} \\ \implies \frac{3 + 0}{2} - \frac{9}{2} \\ \implies \frac{3}{2} - \frac{9}{2} \\ \implies \frac{3 - 9}{2} \\ \implies \frac{ - 6}{2} \\ \implies - 3

Thanku✌
