Question

express the following in terms of angles between 0 and 45 .
sin 59 tan 63

Answer 1

According to the Question

sin 59 + tan 63

Identity of Trigonometry

cos (90 - Ф ) = sin Ф

cot (90 - Ф ) = tan Ф

Hence :-

= cos(90 - 59) + cot(90 - 63)

= cos 31 + cot 27

Required Value = cos 31 + cot 27
