Question

step by step explanation plsssss​

Answer 1

Step-by-step explanation:

sin 0 = 0

cos30 = √3/2

sin30 = 1/2

tan45 = 1

tan30 = 1/√3

cot60 = 1/√3

sec60 = 2

cosec90 = 1

Now , putting this value in the LHS

we get,

$\frac {(0+\frac{\sqrt{3}}{2})(\frac{1}{2} + 1) }{(\frac {1}{\sqrt3}+ \frac {1}{\sqrt3})(2-1)} = \frac{(\frac{\sqrt3}{2})(\frac{3}{2})}{(\frac{2}{\sqrt3})(1)}\\\\ \implies \frac{\sqrt3 \times \sqrt3 \times 3}{2 \times 2\times 2} \\\\\implies \frac{9}{8} \\\\\textsf {LHS = RHS} \\\\\text {\huge {Hence Proved!!}}$

Hope it helps
