Find the length of the major and minor axes of an ellipse with the equation We must first get the equation in either of these two standard forms. A 6 and b 2. Length of major axis 2a 2 6 12 units.
Find c2 c 2 using h h and k k found in Step 2 along with the given coordinates for the foci.
Or if the ellipse looks like this. The standard form of the equation of an ellipse with center hk and major axis parallel to x axis is. Coordinates of the vertices are hak Minor axis length is 2b. FP GP FV GV FV and GV give us the length of the major axis.
