An Elementary Course in Analytic Geometry
The subtangent is the length TM, where M is the foot of the ordinate of the point of
tangency Px ; and the subnormal is the corresponding length MN. As thus taken,
the 'sub- tangent and the subnormal are of the same sign ; ordinarily, however, ...

that in the case of the parabola y 2 = 4 a x , the subnormal is of constant length ...

In all curves the subnormal is a third proportional to the subtangent and the
ordinate; and in the parabola it is a constant (juaiitily, being equal to half the

41 of the former ; at this temperature, therefore, our author found the subtangent
of the atmospheric logarithm equal to the subtangent of Briggs' logarithm in Paris

It is often, however, found convenient in spirals, properly so called, to put r = a; as
it frequently simplifies the dependent reductions. In such case the 4'? (iii Applying
this to the example before us, we have _ 9 value of the subtangent is simply r2 ...

The length of the subtangent is T, : 21". The length of the normal is N = 2 V m' + m'
. The length of the subnormal is N I : 2m. These expressions lead immediately to
several properties of the curve. Thus the expression for the subtangent at once ...

Sunil Kumar Maity. Thus, Subtangent = y y1 and Subnormal = yy1. PT is the
portion of the tangent intercepted between x-axis and the point of contact.
Similarly, PN is the portion of the normal intercepted between x-axis and the point
of contact.
