Question

4) Simplify Sin 60° + Tan 45 cos 30' cot 45° + 5ec30 cosec 50​

Answer 1

Step-by-step explanation:

sin60 + tan45cos30cot45 + 5sec30cosec50

$\frac{\sqrt{3} }{2} + \frac{\sqrt{3} }{2} +5sec^{2} 30\\=> \sqrt{3} + \frac{4}{3}\\=> \frac{3\sqrt{3} +4}{3}$

Identities used:

tanx*cotx = 1

cosec(90-x) = secx
