IF the slope of the tangent to the circle `S=x^2+y^2-13=0` at (2,3) is m, then the point `(m,(-1)/m)` is

If the line lx + my = 1 is a tangent to the circle x^(2) + y^(2) = a^(2) , then the point (l,m) lies on a circle.

If m is the slope of the tangent to the curve e^(y)=1+x^(2) , then

If m is the slope of the tangent to the curve, e^(y) =1 +x^(2) , then,

The slope of the tangent to the curve (y-x^5)^2=x(1+x^2)^2 at the point (1,3) is

The slope of the tangent to the curve (y-x^(5))^(2)=x(1+x^(2))^(2) at the point (1,3) is.
