  1. Tangent

    In geometry, the tangent line to a plane curve at a given point is the straight line that "just touches" the curve at that point. Informally, it is a line through a pair of infinitely close points on the curve. More precisely, a straight line is said to be a tangent of a curve y = f(x) at a point x = c on the curve if the line passes through the point on the curve and has slope f' where f' is the derivative of f. A similar definition applies to space curves and curves in n-dimensional Euclidean space. As it passes through the point where the tangent line and the curve meet, called the point of tangency, the tangent line is "going in the same direction" as the curve, and is thus the best straight-line approximation to the curve at that point. Similarly, the tangent plane to a surface at a given point is the plane that "just touches" the surface at that point. The concept of a tangent is one of the most fundamental notions in differential geometry and has been extensively generalized; see Tangent space. The word tangent comes from the Latin tangere, to touch.

  3. Carl DeHaven:

    It appears that asking is not always a pleasant thing. Could be an aspect of human nature to feel awkward when asking others. To say "Please" we give others the option of assisting us or not. The manner in which we feel about what we ask relates to our feelings about asking. Passion is an element of our saying..."Please...so is the motive. We all ask of others. Why we ask depends mostly on present conditions...those change. I ask others to think a bit before going on some tangent. Doing so could be beneficial to all of us...Please? KnowyerLoved CWD
