gradien garis
Penjelasan dengan langkah-langkah:
i) cari gradien garis singgung = m1
kurva y = x²+ 1
gradien garis singgung m1 = y' = 2x
sejajar garis y = 4x + 1 --> m2 = 4
m1 = m2 = 4
cari titik singgung (x1,y1)
m1 = m2= 4
2x = 4
x = 4/2
x = 2
y = x² + 1 --> y = 2² + 1 = 5
titk singgung (x1, y1)= ( 2, 5)
