Applications of GeoGebra- Spoken Tutorials- Assignments Funded by the National Mission on Education through ICT -------------------------------------------------------------------------------------------------------------- Assignment 1. Construct ellipses with: Foci (± 4, 0) and vertices (± 5, 0) Foci (0, ± 5) and vertices (0, ± 13) Find their centres and equations. Calculate eccentricity and length of latus recti, major and minor axes. 2. Find the coordinates of the foci, vertices and co-vertices Eccentricity and length of major, minor axes and latus rectum for these ellipses: x^2/4 + y^2/25 = 1 36x^2 + 4y^2 = 144
