The eccentricity of an ellipse is defined as For an​ ellipse, so When e is close to​ 0, an ellipse appears to be nearly circular. When e is close to​ 1, an ellipse is very flat. Find an equation of an ellipse with vertices(0,-8) and (0,8) and= 1/2

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

my guess is

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
