y^2/36-x^2/4=1. find the coordinates of the vertices and foci and the equations of the asymptotes for the hyperbola and graph.
**
Standard form of equation for a hyperbola with vertical transverse axis:
(y-k)^2/a^2-(x-h)^2/b^2=1, with (h,k) being the (x,y) coordinates of the center.
..
For given hyperbola, y^2/36-x^2/4=1.
center: (0,0)
a^2=36
a=√36=6
vertices: (0,0�a)=(0,�6)=(0,-6) and (0,6)
..
b^2=4
b=2
c^2=a^2+b^2=36+4=40
c=√40≈6.32
Foci: (0,0�c)=(0,�√40)=(0,-6.32) and (0,6.32)
..
Asymptotes:
slope of asymptotes: �a/b=�6/2=�3
equation of asymptotes: y=3x and y=-3x
see graph below:
y=(36+9x^2)^.5
