Basic Calculus
Outline Differentiation as finding slope Integration as finding area Integration as inverse of differentiation
Limit “Limit” as finding the slope of a curve –The slope of the curve y=mx+c is m. –How about the slope of the curve y=x^2? –Approximately, the slope at x1 is (y2-y1)/(x1-x2) x1x2 y1 y2
Limit x1x2 y1 y2
Differentiation of x^2 x1x2 y1 y2 Let’s find dy/dx at x=x1
Differentiation of x^n
Differentiating a sum of two functions of x
Differentiation of
Chain Rule
Area under curve x Y= f(x) ba
Approximation by Summation xba
Integration: Infinitesimal Approximation by Summation xba … Divide into n stripes, and let n goes to infinity
The Fundamental Theorem of Calculus Integration is antiderivative:
Explaining Fundamental Theorem of Calculus Differentiating area gets curve Differentiating curve gets slope x Y= f(x) ba
