Question

evaluate cos 38 cosec 52/root 3(tan 18 tan 35 tan 60 tan 72 tan 55)​

Answer 1

Step-by-step explanation:

$\frac{ \cos(38) \csc(52) }{ \sqrt{3} \tan(18) \tan(35) \tan(60) \tan(72) \tan(55) }$

$= \frac{ \cos(38) \csc(52) }{ \sqrt{3} \tan(72) \cot(72) \sqrt{3} \tan(35) \cot(35) }$

$= \frac{ \cos(38) \csc(52) }{3}$

$= \frac{ \cos(38) }{3 \sin(52) }$
