Problem : Is the transverse axis of this hyperbola horizontal or vertical: - + = 1 .

Problem : Find a , b , and c of the following hyperbola: 5x ² -3y ² - 20x + 6y + 2 = 0 .

Solution for Problem 2 >>

By completing the square, factoring, and putting the equation in standard form, it is evident that a = , b = , and c = .

Problem : The eccentricity of a hyperbola with center (0, 0) and focus 5, 0) is . What is the standard equation for the hyperbola?

Solution for Problem 3 >>

e = , so c = 5 , a = 3 , and b = = 4 . The locations of the focus and the center mean that the transverse axis is horizontal, and the y ² term is negative. So the standard equation for this hyperbola is - = 1 .
