The lengths of the tangent, normal, subtangent and subnormal are respectively `p`, `q`, `s`, `t` then `p^2:q^2=`

Length of tangent; normal; subtangent and subnormal

Length OF tangent, Normal Subtangent and Subnormal

Lenth OF Tangent || Normal || Subtangent || Subnormal

Q. Species P and S are respectively:

The lengths of tangent, subtangent, normal and subnormal for the curve y=x^(2)+x-1 at (1,1) are A,B,C and D respectively, then their increasing order is

Find the tangent of the angle between the lines whose intercepts on the axes are respectively, p, -q and q, -p .

The tangent and the normal drawn to the curve y=x^(2)=x+4 at P(1,4) cut the X=-axis at A and B respectively. If the length of the subtangent drawn to the curve at P is equal to the length of the subnormal, then the area of the triangle PAB (in sq units) is
