Hi friend,
Here is your answer,
_____________________________________________________________
sec(90°- Ф)cosecФ - tan(90°- Ф)cotФ + cos²25° + cos²65°
3tan27°tan63°
=> cosecФ.cosecФ - cotФ.cotФ + cos²25° + sin (90°-65°)
3tan27°cot(90°-63°)
=> cosec²Ф - cot²Ф + cos²25° + sin²25Ф
3tan27°cot27°
=> 1 + 1
3 * 1
=> 2
