Question

For the hyperbola  which of the following remains constant with change in ‘α’

Solution

Correct option is

Abscissae of foci

 

Let e be the eccentricity of the hyperbola. Then, 

      

Clearly, e varies with α 

Now,   

           

  

Thus, the coordinates of the foci are (±1, 0). 

Clearly, abscissae of foci remain constant.
