Math Problem Statement

Endpoints of Conjugate axis (3,-2), (3,6), length of transverse units is 16 units

Solution

To find the equation of the hyperbola, you are given the following information:

  • The endpoints of the conjugate axis are (3,2)(3, -2) and (3,6)(3, 6).
  • The length of the transverse axis is 16 units.

Step 1: Find the center of the hyperbola

The center of the hyperbola is the midpoint of the conjugate axis. The midpoint between (3,2)(3, -2) and (3,6)(3, 6) can be calculated as:

Midpoint=(3+32,2+62)=(3,2)\text{Midpoint} = \left( \frac{3+3}{2}, \frac{-2+6}{2} \right) = (3, 2)

So, the center of the hyperbola is (3,2)(3, 2).

Step 2: Determine the distance of the conjugate axis

The distance between the endpoints of the conjugate axis is the length of the conjugate axis. The distance between (3,2)(3, -2) and (3,6)(3, 6) is:

Distance=(33)2+(6(2))2=02+(6+2)2=64=8\text{Distance} = \sqrt{(3 - 3)^2 + (6 - (-2))^2} = \sqrt{0^2 + (6 + 2)^2} = \sqrt{64} = 8

Thus, the length of the conjugate axis is 8 units. Since the length of the conjugate axis is 2b2b, we have:

2b=8b=42b = 8 \quad \Rightarrow \quad b = 4

Step 3: Determine the value of aa

The length of the transverse axis is given as 16 units. The length of the transverse axis is 2a2a, so:

2a=16a=82a = 16 \quad \Rightarrow \quad a = 8

Step 4: Write the equation of the hyperbola

Since the conjugate axis is vertical (aligned with the y-axis), and the transverse axis is horizontal (aligned with the x-axis), the standard form of the equation of the hyperbola is:

(xh)2a2(yk)2b2=1\frac{(x - h)^2}{a^2} - \frac{(y - k)^2}{b^2} = 1

where (h,k)(h, k) is the center of the hyperbola, aa is half the length of the transverse axis, and bb is half the length of the conjugate axis. Substituting the known values:

  • h=3h = 3, k=2k = 2,
  • a=8a = 8, so a2=64a^2 = 64,
  • b=4b = 4, so b2=16b^2 = 16.

Thus, the equation of the hyperbola is:

(x3)264(y2)216=1\frac{(x - 3)^2}{64} - \frac{(y - 2)^2}{16} = 1

Final Answer:

The equation of the hyperbola is:

(x3)264(y2)216=1\frac{(x - 3)^2}{64} - \frac{(y - 2)^2}{16} = 1
