cos ec15^(0)+sec15^(0)=

cos ec15^(@)+sec15^(@) is equal to

cosec15^(@)+sec15^(@)=

cos ec15 ^ (@) + sec15 ^ (@) =

cos ec15 ^ (@) + sec15 ^ (@)

"cosec" 15^(@) + sec 15^(@) =

Which of the following number(s) is/are rational? (a)sin 15^(0)(b)cos15^(0)(c)sin15^(0)cos15^(0)(d)sin15^(0)cos75^(0)

cos^(2)75^(0)+cos^(2)15^(0)-cos75^(0)cos15^(0)=

Evaluate: det[[cos15^(0),sin15^(0)sin75^(0),cos75^(0)]]

sin 15^(@) + cos 105 ^(@) = ............ A) 0 B) 2 sin 15 ^(@) C) cos 15^(@) + sin 15^(@) D) sin 15^(@) - cos 15^(@)

Prove that: cos1052^(@)+cos15^(0)=s in75^(0)-s in15^(0)
