If y=5 (sin 100^(@)cos 27^(@) +cos 100^(@)sin 27^(@)) the value of y is :-

The value of (sin25^(@)cos65^(@)+cos25^(@)sin65^(@))/(tan^(2)27^(@)-cos ec^(2)20^(@))

Consider the following inequalities : 1. sin1^(@) lt cos 57^(@) 2. cos60^(@) gt sin 57^(@) Which of the above is/are correct?

The value of sin3^(@)sin27^(@)sin33^(@)sin57^(@)sin63^(@)sin87^(@) can be equal to -

Evaluate the following: (i) (cot40^@)/(tan50^@)-1/2((cos35^@)/(sin55^@)) (ii) ((sin27^@)/(cos63^@))^2-((cos63^@)/(sin27^@))^2

Solve the following: ((sin 27^@)/(cos 63^@))- ((cos 27^@)/(sin 63^@))^2
