Chapter 2 : Limits and Derivatives The idea of a limit is illustrated by secant lines approaching a tangent line. The Book Says: MATH 101 : CALCULUS I – Dr. Faisal Fairag

Slope and Equation of a line MATH 101 : CALCULUS I – Dr. Faisal Fairag How to find the slop of a line? (x 1, y 1 ) (x 2, y 2 ) How to find the equation of a line?

MATH 101 : CALCULUS I – Dr. Faisal Fairag What is the difference ?? The word tangent is derived from the Latin word tangens, which means “touching.” Tangent line Secant line

Is it possible that a line could be tangent and secant in the same time
