Area bounded by the curve f(x) = 
- tan2[x], , (where [.] denotes greatest integer function) and the lines x = 
to x = 
and x-axis is
- tan2[x], , (where [.] denotes greatest integer function) and the lines x = to x = and x-axis isOptions
A.
- 1
- 1B.
C.
D.
- tan1
- tan1Solution
For 
< x < 
; [x] = 1.
f(x) =
- tan2 1
= sec21 - tan21 = 1
Area =
< x < ; [x] = 1.f(x) =
- tan2 1= sec21 - tan21 = 1
Area =
