Secant Line与切线(Tangent Line)的区别 Secant Line与切线(Tangent Line)是几何学中两个至关重要的概念,它们在描述曲线与直线的位置关系时发挥着关键作用。切线是与曲线在某一点仅有一个公共点的直线,而割线则是与曲线有两个公共点的直线。这种几何特征上的差异,使得割线和切线在解决几...
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")...
然而,asymptote 来自希腊语ἀσύμπτωτος,意思是not to fall together,不要碰到一起。据说是Apollonius of Perga在研究圆锥曲线时引入的这个概念,指任何不和作为关注对象的曲线相交的线(line)。汉译渐近线符合asymptote 的当代意义,但是我们还是应当知道其原意,以免在阅读某些旧文...

Tangent lines can be approximated by secant lines, as the distance between the two points of intersection on the curve approaches zero, and the secant line becomes increasingly close to the tangent line. This relationship between secant and tangent lines is not only a crucial mathematical concept ...
Illustrated definition of Secant (line): A line that intersects two or more points on a curve. (From the Latin isecarei to cut) (Note: a line...
A secant line is a line that passes through two or more points on the graph of a curve, while a tangent line is a line that only touches the curve at one point. What is the etymology of secant? The word "secant" comes from the Latin word "secantem", which means "a cutting". Th...
A secant line, also simply called a secant, is a line passing through two points of a curve. As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line. The secant line connec

Let a line that's tangent to a circle at touch the circle at point B and a line that is secant touch the circle at points D and E. Let the tangent line and the secant line intersect at point C. Then, BC squared = DC(DC + DE) What is the difference between a tangent and ...
