Tofind:Tangent line and secant line using graph.
Answer to Problem 1D
Tangent line: touches a curve at a single point whereas A secant line intersects two or more points on the curve.
Explanation of Solution
Given:Tangent line and secant line
Concept used:tangent line gives a slope of the equation and secant line gives solution here.
Calculation:
Tangent line: touches a curve at a point, matching the curves slope there.
(from the Latin tangents means touching like the in the word tangible)
A secant line intersects two or more points on the curve. (from the Latin word secare cut or sever.)
They are the line which extends up-to infinity.
The graph both tangent line secant line
Red curve shows a parabola
The Blue line curve which is tangent line
The green line indicates secant line
Hence Tangent line: touches a curve at a single point whereas A secant line intersects two or more points on the curve.
