Enter a coordinate pair for each the starting and ending points according to the Cartesian coordinate system. Then click on Calculate. The calculator will determine the straight line distance between the two points as well as present the coordinates of each point as entered in the standard designation.
c 2 = a 2 + b 2. The line segment of length 2b perpendicular to the transverse axis whose midpoint is the center is the conjugate axis of the hyperbola. The standard equation for a hyperbola with a vertical transverse axis is - = 1. The center is at (h, k). The distance between the vertices is 2a. The distance between the foci is 2c. c 2 = a 2 + b 2. Every hyperbola has two asymptotes.
