Evaluate sin63^(@)cos27^(@)+cos63^(@)sin27^(@)=

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

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

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^(@))

Show that (cos27^(@)+sin27^(@))/(cos27^(@)-sin27^(@))=cot18^(@)

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 -

(cos^(2)33^(@)-cos^(2)57^(@))/(sin21^(@)-cos21^(@))=
