1 Unit Six AP Clculus Unit 6 Review Definite Integrls Nme Period Dte NON-CALCULATOR SECTION Voculry: Directions Define ech word nd give n exmple. 1. Definite Integrl. Men Vlue Theorem (for definite integrls) Short Answer 3. Under wht conditions re RRAM. LRAM, MRAM nd Trpezoidl method going to e under or over estimtes. Consider things like incresing nd decresing function nd concve up nd down. 4. Descrie the Fundmentl Theorem of Clculus for finding the derivtive of n integrl.. How is the re under curve relted to the definite integrl of function? Hos does the re eteen the curve nd the x xis compre to the definite integrl? Review 6. A lloon rises t the rte of 8 feet per second from point on the ground 6 feet from n oserver. Find the rte of chnge of the ngle of elevtion when the lloon is feet ove the ground.. Find vlue so tht the function 3 x, x 1 f( x) x 1, x 1 is continuous. True Flse questions worth points ech. (If flse give n exmple.) 1. Points of Inflection only occur where the second derivtive chnges from positive to negtive.. If function is integrle on n intervl if is continuous on tht intervl 3. If function is diverentile on n intervl if is continuous on tht intervl 4. Reversing the limits of n integrl will lwys produce negtive vlue.. Using trpezoidl sum to estimte the re under curve on intervl tht is concve down nd positive for ll vlues on tht intervl will underestimte the ctul re. Pge 1 of 6
