1 Review Guide for MAT0 Final Exam Part I. Thursday December 6 th during regular class time. Part is worth 50% of your Final Exam grade. YOUR Syllabus approved calculator can be used on this part of the exam but are not necessary. All work will be done on the test itself; you may NOT use any scratch paper. Partial credit WILL be awarded for partially correct work so be sure to show ALL of your steps. Correct answers without the correct corresponding work are worth nothing. 4 Questions some with parts. Since you are about to finish up this calculus class (hopefully with a passing grade) you should be able to calculate how much time that gives you per problem. Some problems will take MUCH less time than this number whereas some problems may take slightly longer. You may also use YOUR one () 3 x 5 index card (turn in with test) Things you should make sure that you can do! Note: Section numbers have been provided by each topic so that you can go back through your NOTES, HOMEWORK and OLD TESTS to find problems to practice. You can also go back to the class HELP page and view some of the relevant supplemental readings and videos. I have provided a few examples for particular problems for you to practice (you should still find others of those types to practice on your own!). For those that I did not provide examples for you should have no problem finding examples in your notes, HW and on old tests!. Be able to find the absolute max and absolute min of a given continuous function on a closed interval. Extreme Value Theorem (section.7). Like Test 4 problem #.. Be able to find critical numbers (values that make the derivative zero or undefined) and be able to determine open intervals on which a function is increasing and decreasing by creating the appropriate table. Be able to use the first derivative test to determine x values where a function has a relative maximum and a relative minimum (section.9). Like Test 4 problems # 4, 5 3. Be able to find possible points of inflection (the x-values anyway) for a function and be able to determine open intervals on which a function is concave up and concave down by creating the appropriate table. Also be able to tell which possible points of inflection are actually points of inflection (section.0). Like Test 4 problem #7 (except YOU will have to create the table). 4. Know when L Hopital s Rule applies and how to use it to evaluate limits where direct substitution yields the appropriate indeterminate form (HW section. #, ). Like Test 4 problem # 9 BUT be sure to also go back in your notes and HW and practice some non-polynomial fraction type examples! For example.. x x Lim or Lim x0 sin x x 3Lnx

2 5. In section. we did a summary of curve sketching where we put together all of the material we had learned from the previous few sections and applied it to graphing a function. Try the following problem in addition to reviewing what we did in class for section. and what you did on HW! Also see Test 5 Problems #, 0. Sketch the graph of y f x on the axes below given the following information!!!! The Domain of y f x is 0, d The Range of y f x is, a b f 0 f a 0 f f b f c f d The critical numbers (places where f x = 0 or f x = undefined) are x a, b, c a b The "possible" points of inflection (places where f x= 0 or f x= undefined) occur when x a,, c TEST # a a b a b a b a b a b b c c d 0, a a,, b b, cc, d Sign of f x + + Sign of f x a b c d ***** Could you do a problem like this one BACKWARDS? That is to say, if given the graph could you provide Domain, Range, various function values, fill out the table with the appropriate + and signs and give x values for the relative extrema and actual POI?

3 6. Be able to evaluate an indefinite integral (section 3.). Like Test 5 problems # 6 7. One day during the semester you were given the graph of a velocity vs time function and asked various questions about it. This test question will ask you four questions similar to some of those. See below for a second problem that you could use as practice (although YOUR test problem will only have 4 parts). See the last page of this review guide for another problem with MANY parts! The graph given below represents the velocity of an object moving right and left along straight line for 6 seconds. Velocity (meters / second) m/s m/s - m/s - m/s time (seconds) A) Find 3 0 v() t dt B) What does your answer to A) represent? C) What direction is the object moving from 3 seconds to 5 seconds? Explain HOW you know! D) What direction is the object moving from 9 seconds to seconds? Explain HOW you know! E) Where is the object located at the end of its 6 second trip relative to its starting position? F) What is the total distance travelled by the object during its 6 second trip? G) What is the object doing during the time interval,4? H) During what time interval(s) is the object moving but not accelerating?

4 8. Be able to evaluate a definite integral by using the limit definition (section 3.3). You should be able to find MANY problems in your notes and HW to practice! Also see Test 6 problem # (although on your final exam you will NOT be given the limit definition so be sure that you KNOW it). Here is another problem that you could use as practice x x dx using the limit definition of the definite integral. Use a regular partition and choose Find 3 to be the right endpoint. 9. Be able to evaluate a definite integral using the FTC (see YOUR notes and HW from section 3.4). See Test 6 # 3 x x dx and see if you get the same answer as you did when you practiced the limit definition of Try 3 derivative! 0. Be able to find the average value of a function on a given interval. Also be able to find the x value(s) on the given interval that generate the average value (section 3.4). See homework problems # 8, 9 and 0 in section 3.4. See Test 6 # 4. You could also practice the following Find the average value of x x 3 on,. Note: This is the function and interval from question 9. * X k Also be able to find the answer to * What is the value of x on, that gives you the average value? NOTE: The problems on your Final Exam I for # s 8 0 will be much quicker than the practice problems above for # s 8 0!!!!. Be sure to review the second part of the Fundamental Theorem of Calculus (section 3.4). For example, can you do the following problem? Like Test 6 Problems # 6A or 6B (is one way easier to do?) d dx 3 x Find 4 t t dt. Write your answer as a polynomial in standard form with terms in descending order. 4. Be able to evaluate a variety of integrals (both indefinite and definite). Some may require substitution, some may lead to natural logarithms and some may lead to inverse trigonometric function (sections 4., 4., 4.3). See Test #6 ( # 8 - )as examples! Also consider the following x 4x dx x 6x 4 9x 3 dx 6 4 x x 4 dx It is unlikely that you will finish this test in the given amount of time unless you are EXCEPTIONALLY well prepared. You have only 65 minutes to complete as much as you can. This test may prove to be very challenging unless you have taken the necessary steps throughout the semester to learn all of the material we covered. If you haven t figured it out yet, there is no rule that says these problems must be done in the order that they appear on the test. A wise student would have prepared for this test so well by utilizing this study guide that they know exactly what questions are going to be easiest for them and complete those problems first!

5 Here is another problem like #7 with MANY different questions! vt meters/sec time (seconds) -3 Note: Each marking on the time axis represents one () second. An object travelling back and forth along a straight line has a velocity function given by the graph above. Answer the following questions. A. Find 0 v t dt B. What does your answer to part A. represent? C. The slope of the tangent line to the graph on the time interval 0, is zero. What does that mean is happening during this two second time frame? D. When (give answers in the form t, t slowing down? E. At what time(s) does the object change direction? etc.) is the object speeding up, slowing down, neither speeding up nor F. What is the slope of the secant line for this graph and what does it represent? G. Are there any point in time when the slop of the tangent line matches the slope of the secant line? Should there be? H. What is the total distance travelled by the object during the 9 second trip? I. WHERE is the object located at the end of the 9 second trip? (Give and answer like 4 meters to the left of where it started). J. WHEN does the object pass back through the location that it started this trip? K. What is the average value of vt on 0,9? What does this represent AND WHEN does it occur?
