QUESTION :

Express each one of the following in terms of Trigonometric ratios of angles lying between 0* and 45° → sin 59° + cos 56°

SOLUTION :

➡ sin 59° + cos 56°

• sin ( 90 - ø) = cosec ø

➡ sin ( 90° - 31°) + cos 56°

➡ cosec 31° + cos 56°

• cos ( 90° - ø) = sec ø

➡ cosec 31° + cos ( 90° - 34°)

➡ cosec 31° + sec 34°
