2 Pge of The Fundmentl Theorems of Clculus I. If f is continuous on [, b], then the function F( ) = f( t) dt hs derivtive t every point in [, b], nd df d = d d f () t dt = f ( ). II. If f is continuous on [, b], nd if F is ny ntiderivtive of f on [, b], then b f () t dt = Fb ( ) F ( ). Note: These two theorems my be presented in reverse order. Prt II is sometimes clled the Integrl Evlution Theorem. Don t overlook the obvious! d. f () t dt d = 0, becuse the definite integrl is constnt b. f '( ) d = f ( b) f( ) Upgrde for prt I, pplying the Chin Rule g( ) If F( ) = f( t) dt, then df d g( ) = () d d f t dt = f ( g ( )) g ( ). 3 d For emple, sin( ) t dt sin( 3 3 = 3 sin 6 d = (( ) )( ) ( ) An importnt lternte form for prt II Fb ( ) F ( ) f( t) dt = + b [Think of this s: ending vlue = strting vlue plus ccumultion.] For emple, given tht Using the lternte formt, f '( ) d= 4 nd (3) f =, find f (). f () = f(3) + f '( ) d = 35 + ( 4) = 3.
