If the relation between subnormal SN and subtangent ST at any point S on the curve by^(2)=(x+a)^(3) is P(SN)=q(ST)^(2) then (z)/(q) is equal to

The length of the subtangent at any point on the curve y=be^(x/3) is

If the subnormal at any point on the curve y =3 ^(1-k). x ^(k) is of constant length the k equals to :

For the curve by^(2)=(x+a)^(3) the square of subtangent is proportional to

If ST and SN are the lengths of subtangents and subnormals respectively to the curve by^(2)=(x+2a)^(3). then (ST^(2))/(SN) equals (A)1 (B) (8b)/(27) (C) (27b)/(8) (D) ((4b)/(9))

The length of the subnormal to the parabola y^(2)=4ax at any point is equal to

Prove the relation, s_t=u + at - 1/2 a.
