i wanna ask a question too :)
what? now post in the chat for me? lol
i was robbed lol
hey can you help me with a question?
where is it? or what is it? :)
i have to find center, vertices, co-vertices, foci, and eccentricity of an ellipse
eccentricity = .... c/a? gotta look that up again lol
ok thats fine but i have no idea i wasnt in school when this was taught lol
its c/a :) or distance from center to focus/ distance from center to edge
whats the ellipse you got?
(x-3)^2/16 + (y+6)^2/4 = 1
ellipse has the major axis corresponds to the bigger number on bottom; for this thats the x component right?
i think thats the b value
center = 3,-6 and it rides parallel to the x axis a = major axis; and b is the minor axis a = sqrt.16 = 4 b = sqrt.4 = 2 vertexes are (7,-6)(-1,-6)
the minor vertexes are (3,-4)(3,-8)
the eccentricity = sqrt(16+4)/4
eccentricity = sqrt.5
i got that wrong lol
sqrt(16 - 4)/4 sqrt.12/4 sqrt.3 = eccentricity
sqrt(3) ------ ; ill learn to do this eventually lol 2
haha ok so the eccentricity is sqrt3/2? or just sqrt 3
when i do it correctly; and that a big when; it should be sqrt(3)/2
alright
sqrt(hyp-leg)/hyp
what about foci?
