AP EAMCET2006MathematicsHyperbola
If the eccentricity of a hyperbola is 3 ; then the eccentricity of its conjugate hyperbola is :
Options
- A2
- B3
- C3 2
- D2 3
Correct answer
C. 3 2
Step-by-step solution
Let e and e^ are the eccentricities of a hyperbola and its conjugate hyperbola. We know that 1 e^2 + 1 (e^ )^2 =1 1 3 + 1 (e^ )^2 =1 1 (e^ )^2 = 2 3 e^ = 3 2
