A. b2/a2
B. a2/b2
C. (a2+1)/(b2-1)
D. none of these
tan (1/2 cos-1(0)) =
If θ= Sin-1 x+ Cos-1 x+ Tan-1 x, 0≤x≤1, then the smallest interval in which θ lies is given by
If cos-1 x= cot-1(4/3)+Tan-1(1/7), then x=
If sin-1 (3/5)+sin-1(5/13)= sin-1 x, then x=
Tan-1 5/6+ 1/2 Tan-1 11/60 =
The range of Sin-1 5x is
Sin (4 arc Tan-11/3) =
