In geometry, the subtangent and related terms are certain line segments defined using the line tangent to a curve at a given point and the coordinate axes.

mathematics The projection of a normal of a curve onto the x-axis; see subtangent This disambiguation page lists articles associated with the title Subnormal.

subdifferential, that is, in the figure above, one may draw a horizontal "subtangent line" to the graph of f at (x0, f(x0)).

one other point besides P on it were known; hence, if the length of the subtangent MT could be found (thus determining the point T), then the line TP would.

He found for the subtangent of a curve f(x, y) 0 an expression equivalent to − y ∂ f ∂ y ∂ f ∂ x.
