Find the equation for the ellipse that satisfies the given conditions: b = 3, c = 4, centre at the origin; foci on the x axis.
Find the equation for the ellipse that satisfies the given conditions: b = 3, c = 4, centre at the origin; foci on the x axis.

Given:

    \[b\text{ }=\text{ }3,\text{ }c\text{ }=\text{ }4,\]

focus at the beginning and foci on the x-axis.

Since the foci are on the x-axis, the significant hub is along the x-axis.

In this way, the condition of the ellipse will be of the structure

    \[{{x}^{2}}/{{a}^{2}}~+\text{ }{{y}^{2}}/{{b}^{2}}~=\text{ }1\]

, where ‘a‘ is the semi-significant pivot.

Then, at that point,

    \[b\text{ }=\text{ }3\text{ }and\text{ }c\text{ }=\text{ }4.\]

It is realized that

    \[{{a}^{2}}~=\text{ }{{b}^{2~}}+\text{ }{{c}^{2}}.\]

    \[{{a}^{2}}~=\text{ }{{3}^{2~}}+\text{ }{{4}^{2}}\]

    \[=\text{ }9\text{ }+\text{ }16\]

    \[=25\]

    \[a\text{ }=\text{ }\surd 25\]

    \[=\text{ }5\]

∴ The condition of the ellipse is

    \[{{x}^{2}}/{{5}^{2}}~+\text{ }{{y}^{2}}/{{3}^{2}}~or\text{ }{{x}^{2}}/25\text{ }+\text{ }{{y}^{2}}/9\text{ }=\text{ }1\]
