given two points with the coordinates (1, 2) and (4, 6) respectively.. find out the equation of the tangention line crossing to the line at (1,2)

soalan diubah..

la .. coordinat ke? mee x pernah jawab soklan coordinat dlm ujian

pinguin · Post time 2-1-2008 04:28 PM

dia pancung dekat titik (1,2) lah.. kan dah bgtau... xbacer soalan betul2..

ramai2nya kanak2 kat sini, mcm tak sesuai je i nak interframe

method ..alamak..cmni kot....(6-2)/(4-2) = 4/3 ..jadi m=4/3

so equation antara line => y=4/3x +c

errr..tangent gradient

(4/3) X (m2) = -1

m2 = -3/4

y = -3/4x + c (Tangent equation)

2 = -3/4 (1) +c

c = 2 3/4

y= -3/4x + 2 3/4

y=-3/4x +11/4

4y= -3x+11

ala kak makh...mari2 bersosiol ngan kanak2 seperti kami..kami eprlukan kasey sayang

given 2 point..

m1 = (y2-y1)/(x2-x1) = (6-2)/(4-1) = 4/3

m2 = -3/4

y2= -3/4 x + C masukkan titk (1,2) ---> C = 2 3/4

maka y2 = -3/4 x + 2 3/4

kalau aku xsalah kira la..
