Question

Evaluate the following
3+ sin^2 60° + cosec²30°\5+ cos²6ot sec²30°​

Answer 1

Answer:

93/64

Step-by-step explanation:

Note: The question doesnot seem correct as the addition and multiplication signs seem to have been misplaced. But anyway following is the method

3+ sin^2 60° + cosec²30°\5+ cos²6ot sec²30°

= 3 + (√3/2)² + (2)² / 5 + (1/2)² * (2/√3)²

= 3 + (3/4 + 4) / 5 + 1/4*4/3

= 31/4 / 16/3

= 31/4 *  3/16

= 93/64.
