If A is the area in the first quadrant enclosed by the curve C:2x2-y+1=0, the tangent to C at the point 1, 3 and the line x+y=1, then the value of 60A is................

Solution

Given,

y=2x2+1

Now tangent to above equation at 1,3 is given by,

y-3=4x-1

y=4x-1

Now plotting the diagram we get,

Required area of bounded region will be,

A=012x2+1dx-area of QOT -area of PQR +area of QRS

A=23+1-12-98+940=1640

60A=16
