Question

qn on straight lines

Answer 1

Throught the origin O , a straight line is drawn to cut the lines y=m1x+c1 and y=m2x+c2 at Q and R respectively.Find the locus od point P on this variable line ,such that OP is the geometric mean between OQ and OR

Answer 2

srry "through"

Answer 3

dumbcow can u hlp?

Answer 4

sorry i was away for a moment.

so Q is some point (x1,y1) on line 1
R is some point (x2,y2) on line 2

OQ = sqrt(x1^2 + y1^2)
OR = sqrt(x2^2 +y2^2)

geometric mean is square root of product
OP = sqrt(sqrt((x1^2 + y1^2)(x2^2 + y2^2)))
