Find the eccentricity of the hyperbola 15y2 522 15 What is
     Find the eccentricity of the hyperbola.  15y^2 - 52^2 = 15  What is the eccentricity?  (Type an integer or decimal rounded to the nearest tenth as needed.) 
  
  Solution
15y^2 - 5x^2 =15
15y^2 /15 -5x^2 = 15/15
y^2 -(x^2)/3 =1
comparing it a = 1 b = sqrt(3)
e = sqrt [ (a^2+b^2) /a)
e = sqrt [(1+3)/1)
e = sqrt(4)
e=2
