Hyperbola Math Examples
Here is the sketch for this hyperbola.
Hyperbola math examples. X 2 a 2 y 2 b 2 1. We need to. One vertex is at a 0 and the other is at a 0 the asymptotes are the straight lines. B y2 9 x 2 2 1 y 2 9 x 2 2 1 show solution.
9 4 b2 substitute 3 for c 2 for a step 5. A more formal definition of a hyperbola is a collection of all points whose distances to two fixed points called foci plural for. The diagonals of the rectangle are the asymptotes and their equations are. Notice that it is not a function since for each x value there are two y values.
General equation of north south hyperbola. Finding the equation of a hyperbola centered at h k given its foci and vertices what is the standard form equation of the hyperbola that has vertices at latex left 0 2 right latex and latex left 6 2 right latex and foci at latex left 2 2 right latex and latex left 8 2 right latex. For problems 4 5 complete the square on the x x and y y portions of the equation and write the equation into the standard form of the equation of the hyperbola. Here s another example of a north south hyperbola.
Since the transverse axis is horizontal the standard form of the hyperbola is or. This is a hyperbola centered at the origin with foci on the y axis and y intercepts 2 and 2 the points 5 2 5 2 52 5 2 determine the fundamental rectangle. A hyperbola is a type of conic section that looks somewhat like a letter x. A hyperbola can open to the left and right or open up and down.
3 x 1 2 y 1 2 2 1 3 x 1 2 y 1 2 2 1 solution. 4x2 32x y2 4y 24 0 4 x 2 32 x y 2 4 y 24 0 solution. A hyperbola is a set of all points p such that the difference between the distances from p to the foci f 1 and f 2 are a constant k before learning how to graph a hyperbola from its equation get familiar with the vocabulary words and diagrams below. By placing a hyperbola on an x y graph centered over the x axis and y axis the equation of the curve is.
In the graph 2 c 6 and 2 a 4 or c 3 a 2. In this case the hyperbola will open up and down since the x x term has the minus sign. Where are the 2 foci for this hyperbola. Remember that since there is a y 2 term by itself we had to have k 0 k 0.
