JEE Main 2021 (26 Feb, Shift 2) Maths Q63: Area Under Curves

Question

Let $A_1$ be the area of the region bounded by the curves $y=\sin x$, $y=\cos x$ and $y$-axis in the first quadrant. Also, let $A_2$ be the area of the region bounded by the curves $y=\sin x$, $y=\cos x$, $x$-axis and $x=\frac{\pi}{2}$ in the first quadrant. Then,

Accepted Answer

Option 2: $A_1 : A_2 = 1 : \sqrt{2}$ and $A_1 + A_2 = 1$

Answer

$A_1 : A_2 = 1 : 2$ and $A_1 + A_2 = 1$

Answer

$A_1 : A_2 = 1 : \sqrt{2}$ and $A_1 + A_2 = 1$

Answer

$A_1 = A_2$ and $A_1 + A_2 = \sqrt{2}$

Answer

$2A_1 = A_2$ and $A_1 + A_2 = 1 + \sqrt{2}$
