Area under the curveEasy
Question
The area bounded by circle x2 + y2 = 4 ;
curve y =
(where [ . ] is G.I.F.) and the x-axis ; is
curve y =
(where [ . ] is G.I.F.) and the x-axis ; isOptions
A.π/3 + √3 square unit
B.2π/3 + √3 square unit
C.π/4 + √3 square unit
D.π/2 + √3 square unit
Solution
For x ∈ [- 2, 2] ; - 
cos
≥ cos2 
i.e.
Also,
∴
∴ y = 1
