help finding center, lengthof major axis, equation of the major axis, and coordinates of the extrema points at the end of the axes for each ellipse

Question

regan · Answer

is the elipse given parametrically or implicitly?

anonymous · Answer

$${x}^2/81+{y}^2/16=1$$

regan · Answer

ok the elipse general formula is
$$x^{2}/a ^{2}+y^{2}/b^{2}=1$$
where a and b are the length of each axis. the rest can be derive intuitivly from geometry and algebra
