Question

2 cos2 90 + 4 cos2 45 + tan2 60+ 3 cosec2 60 /(3 sec 60 - 1/2 sec2 45 + 2 cosec 30)

Answer 1

Answer:

2cos²90°+4cos²45°+tan²60°+$\frac{3cosec²60°} {3sec60°-1/2sec²45°+2cisrc30°}$

Step-by-step explanation:

Answer 2

Answer:

530

Step-by-step explanation:

2 cos2 90 + 4 cos2 45 + tan2 60+ 3 cosec2 60 /(3 sec 60 - 1/2 sec2 45 + 2 cosec 30)

according to dalton theory

cos2******cos2=cos500050

so the answer is 530
