Course: Analysis, desegregation and ODE, Module 2 decided and forbid Integrals Course: Calculus (Analysis, desegregation and ODE) Lect. Sonnet Hung Q. Nguyen USTH, March 2012 mental ability Integral as (signed) sweep to a lower situate contract Riemann sums and definite integrals Basic properties of Riemann integrals Fundamental Theorem of Calculus illegitimate integrals Module 2: Definite and Improper Integrals Dr Sonnet Nguyen 2/60 1 Course: Analysis, Integration and ODE, Module 2 Introduction to Definite Integral Two main points of displace: o Integral as (signed) area under curve o Integral as antiderivative Module 2: Definite and Improper Integrals 3/60 Area beneath Curves get hold the area of the contribution S that lies under the curve y = f ( x) from a to b. This means that S is bounded by the graph of a straight function f [where f ( x) ? 0], the vertical lines x = a and x = b, and the x-axis. Module 2: Definite and Improper Integrals Dr Sonnet Nguyen 4/60 2 Course: Analysis, Integration and ODE, Module 2 Area Under Curves To adjudicate the area problem we have to ask ourselves: What is the inwardness of the book of account area? This question is easy to coiffe for portions with straight sides.

For a rectangle, the area is defined as the carrefour of the length and the width. Module 2: Definite and Improper Integrals 5/60 Area Under Curves Rectangles suggest the following unsophisticated idea: We first approximate the region by rectangles and therefore we take the limit of the areas of these rectangles as w! e increase the add together of rectangles. Module 2: Definite and Improper Integrals Dr Sonnet Nguyen 6/60 3 Course: Analysis, Integration and ODE, Module 2 Area Under Curves To strike the area of the region S that lies under the curve y = f ( x) from a to b, we bugger off by subdividing S into n strips S1 ,...,Sn of equal (b ? a) . These strips divide the breakup [a, b] into n n subintervals [ x0 , x1 ], [ x1 ,...If you want to get a total essay, order it on our website: BestEssayCheap.com
