foki 2pir^2+16pir

Lösung

foki

2 π r^{2} + 16 π r

Lösung

(- 4, \frac{- 256 π ^{2} + 1}{8 π})

Schritte zur Lösung

Rewrite

y = 2 π r^{2} + 16 π r

in the standard form

4 \cdot \frac{1}{8 π} (y - (- 32 π)) = (r - (- 4))^{2}

(h, k) = (- 4, - 32 π), p = \frac{1}{8 π}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(- 4, - 32 π)

along the y-axis

(- 4, - 32 π + p)

= (- 4, - 32 π + \frac{1}{8 π})

Fasse zusammen
