Given sin 59° + cos 56°

sin 59° + cos 56° = sin (90° - 31°) + cos (90° - 34°)

= cos 31° + sin 34°

[sin (90 - 0) = cos , cos (90 - 0) = sin 0]

Hence, sin 59° + cos 56° = cos 31°. sin 34°

(ii) SOLUTION :

Given tan 65° + cot 49°

tan 65° + cot 49° = tan (90° -25°) + cot (90° - 41°)

= cot 25° + tan 41°

[tan (90 - 0) = cot 8, cot (90 - 0) = tan 0]

Hence, tan 65° + cot 49° = cot 25° + tan 41°
