Question
If at any point S of the curve by2 = (x + a)3 the relation between subnormal SN and subtangent ST be p(SN) = q(ST)2 then p/q is equal to-
Options
A.
B.
C.b/a
D.None of these
Solution
If at any point by2 = (x + a)3 curve
sn = Subnormal
st = subtangent
p(SN) = q(ST)2
So by2 = (x + a)3
2by
= 3(x + a)2
S. N. = y ×
S. T. ⇒
sn = Subnormal
st = subtangent
p(SN) = q(ST)2
So by2 = (x + a)3
2by
