Calculus Cheat Sheet Visit for a complete set of Calculus notes. 2005 Paul Dawkins Integrals Definitions Definite Integral: Suppose ()fx is continuous on [ ],ab. Divide [ ],ab into n subintervals of width x a nd choose *ix from each interval. Then ()()*1liminbanif x dxf xx == . Anti-Derivative : A n anti-derivative of ()fx is a function, ( )Fx, such that ( ) ( )F x fx =. Indefinite Integral :( )( )f x dxF xc=+ where ( )Fx is an anti-derivative of ( )fx.

7 13x x A Bx C Bx A C22+ =+ +− + −( ) 4 Set coefficients equal to get a system and solve to get constants. 7 13 4 0 4 3 16 A B C B A C A B C += −= −= === An alternate method that works to find constants. Start with setting numerators equal in sometimes previous example : 7 13 4x x A x Bx C x22+ = ++ + −( ) ( )( 1). Chose nice values ...
