The area of the region bounded by the curves y= e ^x, y= x and lines x=1, x=2 is
Options
- A( e -1)^2 sq . units
- B( e ^2- e +1 ) sq . units
- C( e ^2- e +1-2 2 ) sq . units
- D( e ^2+ e -2 2 ) sq. units
Correct answer
C. ( e ^2- e +1-2 2 ) sq . units
Step-by-step solution
aligned & Required Area & = ₁^2 ( e ^x- x ) d x & = [ e ^x ]₁^2- ₁^2 1 x ~d x & = ( e ^2- e )- [x x- ₁^2 1 ~d x ] & = ( e ^2- e )-[x x-x]₁^2 & = ( e ^2- e )-[(2 2-2)-(1 1-1)] & = e ^2- e -(2 2-2-0+1) & = e ^2- e -(2 2-1) & = ( e ^2- e +1-2 2 ) sq. units aligned
