Question

What are the vertices and co vertices of the ellipse x^2/4 + y^2/25=1
I actually have no idea how to even start to solve this problem, so any help will be appreciated.
Steps on how this problem is solved are also appreciated.

Answer 1

the vertices are at the ends of the major axis, and the covertices are on the minor axis. So, since 25 > 4, the vertices are on the y-axis.

when x=0, y=5
when y=0, x=2

So, the vertices are at (0,±5)
the covertices are at (±2,0)

Looks like you need to review the section where this was explained. With graphs, I'm sure.
