" (ii) "-47^(@)30^(@)

Find the radian measures corresponding to the following degree measures:(i) 25^o (ii) - 47^o30prime (iii) 240^o (iv) 520^o

The value of (tan 47^(@) + tan 43^(@))/(1-tan 47^(@) tan 43^(@)) is

cos(47^@) cos (13^@) - sin (47^@) sin(13^@)= .........

The value of (sin43^(@)cos47^(@)+cos43^(@)sin47^(@)) is

The value of (sin43^(@) Cos47^(@) + cos43^(@) sin47^(@)) is …….. .

Convert into radian measure -47^(@)30'

Without using Trigonometric tables, evaluate:- 2(sin43^@)/(cos47^@)-(cot30^@)/(tan60^@)-sqrt2 sin45^@ .

Common factor of (47^(43)+43^(43)) and (47^(47)+43^(47))
