Manipal MET2014MathematicsArea Under Curves
The area enclosed by the curves |y+x| 1 , |y-x| 1 and 2 x^2+2 y^y=1 is
Options
- A(2+ 2 ) sq units
- B(2- 2 ) sq units
- C(3+ 2 ) sq units
- D(3- 4 ) sq units
Correct answer
B. (2- 2 ) sq units
Step-by-step solution
The curves y+x 1 and |y-x| 1 form a square A B C D and 2 x^2+2 y^2=1 is a circle of radius 1 2 and centre (0,0) . aligned & Required Area &= Area of square - Area of circle &= (2- 2 ) sq units aligned
