If the question is bracket one then the answer is 1.As. Sin15/cos15*sin25/cos25*sin60/cos60*sin65/cos65*sin75/cos75 [as tan15 =sin15/cos15]. Sin15/cos15*sin25/cos25*sin60/cos60*sin(90-25)/cos(90-25)*sin(90-15)/cos(90-15). Sin15/cos15*sin25/cos25*sin60/cos60*cos25/sin25*cos15/sin15. [Now on solving we get]. √3/2*2/√3 =1
