Let T and C respectively, be the transverse and conjugate axes of the hyperbola 16x2-y2+64x+4y+44=0. Then the area of the region above the parabola x2=y+4, below the transverse axis T and on the right of the conjugate axis C is:
  1. 46+443
  2. 46+283
  3. 46-443
  4. 46-283

Solution

Given,

Equation of hyperbola,

16x2+4x-y2-4y+44=0

16(x+2)2-64-(y-2)2+4+44=0

16x+22-y-22=16

x+221-y-2216=1

Hence, equation of conjugate axis will be x=-2 and equation of transverse axis is given by y=2,

Now plotting the diagram of parabola x2=y+4 and x=-2 & y=2 we get,

 

Now from above diagram, the area of the bounded region is given by,

A=-262-x2-4dx

A=-266-x2dx=6x-x33-26

A=66-663--12+83

A=1263+283

A=46+283
