IfTan-1(1/7)= α, Tan-1(1/3)=β then cos 2α =
Cos (sin-13/5+Sin-1 5/13)=
The range of Sin-1 x - Cos-1 x is
The range of Sin-1 x+ Cos-1 x is
The ascending order of A= Sin-1(log32),B= Cos-1(log3(1/2)), C=Tan-1(log1/3 2) is
Sin-1(24/25) +Tan-1(5/12) =
Tan-1(cot x) - Tan-1(cot 2x)=
If Sin-1 x+ Sin-1 y+ Sin-1 z=π then x2+y2+z2+2xyz=
If Tan-1 x+ Tan-1 y+ Tan-1 z=π, then x+y+z=
Sin-1 (16/65) +2 Tan-1 (1/5) =
