Question
If the relation between subnormal 'SN' and subtangent 'ST' at any point on the curve by 
is 
then 
Hint:
We are given a curve. We are given the relation between the subtangent and the subnormal. We have to find the ratio of the variables p and q. We will first find the values of subtangent and subnormal using the formulae. Then we will find the ratio.
The correct answer is:
The given curve is 
.
The relation between subtangent "ST" and subnormal is "SN" is p(SN) = q(ST)2.
We have to find the ratio of 
.
Subtangent: It is the projection of tangent on x-axis from the x intercept to point of tangency.
Subnormal: It is the projection of normal on x-axis from the x intercept to point of tangency.
The formula of subtangent is ST= 
The formula of subnormal is SN = 
we will differentiate the curve w.r.t x
Now, p(SN) = q(ST)2
For such questions, we should know the formulas of subnormal and subtangent.
