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")...
A line that intersects two or more points on a curve. (From the Latin secare "to cut") (Note: a line that just touches a curve at a point and matches the curve's slope there is called a "tangent".)See: Secant (function)Tangent...
File,意思是排成一行行,比如walk in a file(排成一对走)或者rank and file(国际象棋棋盘上空格的行与列),其它的意思如档案、锉刀等应该都是引申义。File 的拉丁语词源filum,本身就是thread,line 的意思。而filing,英文有个意思是锯末,锯铁块得到的iron filing 历史上恰好是演示法拉第的...
Tangent lines. Secant and Tangent Segments A tangent segment is a point of a tangent line between the point of contact and a point outside the circle. A secant segment is the part of a secant line that joins a point outside the circle to the farther intersection point of the secant and...

The general equation of a line is y = mx + b , where m is the slope of the line and b is the y -intercept. For example, find the slope of the line f ( x ) = 2 x 1, shown in Figure 15.1(a).doi:10.1007/978-3-642-79758-3_15Christopher T. J. Dodson...
Given circle O, tangent line (PA) and secant line (PBC) intersect at point P. Find the value(s) of x given that angle p=38°,m(CA)=2x2-13x, and mBA⏜=x2+2x. Please read question below.This...
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 ...
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 ...
Geometrically, the limit of the secant lines is the tangent line. For a hyperbolic secant squared ( sech 2 ) pulse. However, he felt that his countrymen would have surpassed the secants. is the slope of the secant line between and. It derives from the trigonometric relation ( secant ) be...
