ok

OpenStudy (anonymous):

equation of ellipse=\[(x^2/a^2)+(y^2/b^2)=1\]

OpenStudy (anonymous):

whats a and b?

OpenStudy (anonymous):

it can be thought as the distance from center to the vertex

OpenStudy (anonymous):

(6,8) isx,y?

OpenStudy (anonymous):

a=4,b=3

OpenStudy (anonymous):

I will give you an example

OpenStudy (anonymous):

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

picture=1000 words....look into that pic..you will get it

OpenStudy (anonymous):

i still dont get it

OpenStudy (anonymous):

what is the length of the horizontal axis?8...so the distance from center to any of the vertex is 4

OpenStudy (anonymous):

and the vertical axis length is 6 so distance=3

OpenStudy (anonymous):

a=point where ellipse cuts the x-axis,b=point where ellipse cuts the y-axis

OpenStudy (anonymous):

ok?

OpenStudy (anonymous):

still didnt get that?

OpenStudy (anonymous):

the equation is \[(x-4)^2+(y-3)^2=1\]
