Question

Evaluate sec2 54°-cot2 36°/cosec2 57°-tan2 33° + 2 sin2 38°sec2 52°-sin2 45°​

Answer 1

Answer:

(sec²54 - cot²36)/(cosec²57 - tan²33 + 2sin²38*sec²52 - sin²45)

= (sec²54 - tan²54)/(cosec²57-cot²57 + 2cos²52*sec²52 - sin²45 )

= (1)/(1+2cos²52*1/cos²52 -(1/√2)² )

=1/(1+2(1) - 1/2)

=1/(3-1/2)

=1/(5/2)

=2/5
