Given the equation of a hyperpola #(x+2)^2/a-(y-1)^2/16=1# find the coordinates of c,the foci and the vertices?
1 Answer
The center is:
The vertices are:
The foci are:
Explanation:
Given:
We need to make a few minor changes, to equation [1], so that it is in the standard form of equation [2]:
Please observe that we wrote
We know that the center of equation [2] is
Matching this with equation [1.1], we observe that the center is:
We know that the vertices of equation [2] are
Matching this with equation [1.1] we observe that the vertices are:
We know that the foci of equation [2] are
Matching this with equation [1.1] we observe that the foci are:
