serta panjang sumbu mayor 8 ialah ….
F(p – c, q) = (1,2) p – c = 1
F(p + c, q) = (5,2) p + c = 5
-2c = -4
c = 2
p – c = 1 ➙ p = 1 + 2 = 3
q = 2
a² + b² + c² ⇒ 4² = b² + 2²
b = √16 – 4
= √12
Makara persamaannya:
(x – 3)² ₊ (y – 2)² ₌ 1
16 12
3(x – 3)² + 4(y – 2)² = 4
3x² – 18x + 27 + 4y² – 16y + 16 – 48 = 0
3x² + 4y² – 18x – 16y – 5 = 0
3x² + 4y² – 18x – 16y – 5 = 0
