Answer 2

Answer:

$Value \: of \\ cosec^{2}30\degree - sin^{2}45\degree -sec^{2}60\degree=-\frac{1}{2}$

Step-by-step explanation:

$Value \: of \\ cosec^{2}30\degree - sin^{2}45\degree -sec^{2}60\degree\\=2^{2}-\left(\frac{1}{\sqrt{2}}\right)^{2}-2^{2}\\=4-\frac{1}{2}-4\\=-\frac{1}{2}$

Therefore,

$Value \: of \\ cosec^{2}30\degree - sin^{2}45\degree -sec^{2}60\degree=-\frac{1}{2}$
