sin690 ^ (@) cos930 ^ (@) + tan (-765 ^ (@)) cos ec (-1170 ^ (@))

The value of sin 0^(@) + cos 30^(@) - tan 45^(@) + cosec 60^(@) + cot 90^(@) is equal to

sin765^(@)

When (2 sin 60^(@) cos 30^(@) cosec 45^(@))/(tan 45^(@) cos 60^(@) sin 45^(@)) is simplified , we get

Let a=cos 0^@ sin² 270^@ - 2 cos 180^@ tan 45^@b=3 sin 180^@ *sec 180^@ + 2 cosec 90^@ - cos 360^@c=2 sec^2 pi cos 0^@ + 3 sin^2 (3 pi)/2-cosec pi/2 and d= tan pi cos (3 pi)/2+ sec 2 pi - cosec (3 pi)/2Find the value of (a+b+c+d).

Find the value of (i) sin (765^(@)) (ii) cosec (-1110^(@)) (iii) cot (-600^(@))

Evaluate : (sin 30^(@) + tan45^(@) - cosec 60^(@))/(sec 30^(@) + cos 60^(@) + cot 45^(@))

((cos 9^@+sin 81^@)(sec 9^@+ cosec 81^@))/(sin 56^@ sec 34^@+ cos 25^@ cosec 65^@) =?

The value of sin^2 42^@+ sin^2 48^@+ tan^2 60^@- cosec 30^@ is equal to : sin^2 42^@+ sin^2 48^@+ tan^2 60^@- cosec 30^@ का मान ज्ञात करें |
