Let SS be the region bounded by the curves y=x3y = {x}^{3} and y2=x{y}^{2} = x. The curve y=2∣x∣y = 2\left|x\right| divides SS into two regions of areas R1{R}_{1} and R2{R}_{2}. If max∣R1,R2∣=R2max\left|{R}_{1}, {R}_{2}\right| = {R}_{2}, then R2R1\dfrac{{R}_{2}}{{R}_{1}} is equal to ______Let S be the region bounded by the curves y = x ^ 3 and y ^ 2 = x . The curve y = 2|x| divides S into two regions of

Step-by-step solution

Let S be the region bounded by the curves y = x ^ 3 and y ^ 2 = x . The curve y = 2|x| divides S into two regions of

Intersection point of y2=x and y=2∣x∣{y}^{2} = x \text{ and } y = 2\left|x\right| in the first quadrant will be \left(\dfrac{1}{4}, \dfrac{1}{2}\right)</p><p>Also,intersectionpointof</p><p>Also, intersection point ofy = {x}^{3} \text{ and } {y}^{2} = xinfirstquadrantwillbe(1,1)in first quadrant will be \left(1, 1\right)

Area of the region S=∫01(x−x3)dxS = {∫}_{0}^{1}( \sqrt{x} - {x}^{3} )dx =[2x323−x44]10= {\left[\dfrac{2{x}^{\dfrac{3}{2}}}{3} - \dfrac{{x}^{4}}{4}\right]}_{1}^{0} =512= \dfrac{5}{12}

Area of region R1=∫014(x−2x)dx{R}_{1} = {∫}_{0}^{\dfrac{1}{4}}\left(\sqrt{x} - 2x\right)dx =[2x323−x2]014=148= {\left[\dfrac{2{x}^{\dfrac{3}{2}}}{3} - {x}^{2}\right]}_{0}^{\dfrac{1}{4}} = \dfrac{1}{48}

∴R2=S−R1=1948∴ {R}_{2} = S - {R}_{1} = \dfrac{19}{48}

So, R2R1=19\dfrac{{R}_{2}}{{R}_{1}} = 19
