sin 30° + tan 45º - cosec 60°
_______________________
sec 30° + cos 60° + cot 45°
Answers
Answer:
given that
\frac{(sin30 + tan45 - cosec60)}{(sec30 + cos60 + cot45)}(sec30+cos60+cot45)(sin30+tan45−cosec60)
\frac{ \frac{1}{2}+1- \frac{2}{ \sqrt{3}} }{ \frac{2}{ \sqrt{3}}+ \frac{1}{2}+1}32+21+121+1−32
\frac{ \sqrt{3}+2 \sqrt{3} - 4 }{4 + \sqrt{3} + 2 \sqrt{3} }4+3+233+23−4
\frac{ 3 \sqrt{3} - 4 }{4 + 3 \sqrt{3} }4+3333−4
Rationalise the denominator
\frac{ 3 \sqrt{3} - 4 }{4 + 3 \sqrt{3} } * \frac{ 3 \sqrt{3} - 4 }{3 \sqrt{3} - 4 }4+3333−4∗33−433−4
\frac{(3 \sqrt{3} - 4 )^2}{ (3 \sqrt{3} )^2-(4)^2 }(33)2−(4)2(33−4)2
\frac{27+16-24 \sqrt{3} }{27-16}27−1627+16−243
\frac{43-24 \sqrt{3} }{11}1143−243
