A tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".)A secant line intersects two or more points on a curve. (From the Latin secare "cut or sever")...
Let A=(x,y)A=(x,y) be a point on the Euclidean plane and denote by αα the angle going counterclockwise from the positive half of the horizontal axis and the line segment connecting (0,0)(0,0) and AA. (Observe how we said that αα goes from one line to the other and not ...
They can intersect to develop a product such that the length of the square of the tangent segment is the product of the length of the external part of the secant line and the sum of the external and internal parts of the secant.
Slope of Secant Line Formula is called an Average rate of change. A secant line is the one joining two points on a function. Practice questions online.
On singular varieties having an extremal secant line Let X be a nondegenerate subvariety of degree d and codimension e in the projective space n. If X is smooth, any multisecant line to X cuts X along a 0-dim... Bertin,Marie-Amélie - 《Communications in Algebra》 被引量: 11发表: ...
Formula x3+3⋅x2+12⋅x+8x3+3⋅x2+12⋅x+8 Secant method The secant method can be thought of as a finite difference approximation of Newton's method, where a derivative is replaced by a secant line. We use the root of a secant line (the value of x such that y=0) as a ...
(Observe how we said that α goes from one line to the other and not that it is between them. Because of that, we often call α a directed angle.) Clearly, such α can be larger than 90 degrees. Even better - it can go beyond the full angle of 360 degrees! In that case, we ...

Roughly speaking, we find that the secant line varieties do not have the expected dimension when the partition λ is “unbalanced,” i.e., if d1≥d2+⋯+dr. The structure of the paper is as follows: in Sect. 2, we give a description of how the problem (via Terracini’s lemma) ...
