Question

Find the length of the major axis of the equation
x^2 + 4y^2 = 4

Answer 1

@dusty

Answer 2

divide by 4 ... what do you get?

Answer 3

my answer is 2 but idk if its right or wrong

Answer 4

reduce it to the form of \[x ^{2}/a ^{2} + y ^{2}/b ^{2}= 1\]

Answer 5

you should get \[x ^{2}/4 + y ^{2}/1 = 1 \]

Answer 6

length of the major axis is ' 2a ' if a>b and is ' 2b ' if b>a

Answer 7

so for b i have to put 1

Answer 8

yes . a^2 = 4 so a=2 and b^2=1 so b=1 .. as a>b , length is 2a

Answer 9

ohh.. thank you :)
