foci x^2+16y^2=1

foci

(\frac{15}{4}, 0), (- \frac{15}{4}, 0)

Solution steps

(h + c, k), (h - c, k)

Calculate ellipse properties

x^{2} + 16 y^{2} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 1, b = \frac{1}{4}

(0 + c, 0), (0 - c, 0)

Compute

c :

c = 1^{2} - (\frac{1}{4})^{2} : \frac{15}{4}

(0 + \frac{15}{4}, 0), (0 - \frac{15}{4}, 0)

Refine

(\frac{15}{4}, 0), (- \frac{15}{4}, 0)
