The student is expected to seek college credit, college placement, or both from the college of his/her choice. The student is required to use a graphing calculator and must have access to the graphing calculator at school and at home.

COURSE DESCRIPTION: AP Calculus BC extends the concepts of limits, differentiation, and integration studied in AP Calculus AB to include sequences, infinite series, and parametric, polar and vector valued functions. More attention is given to techniques of integration using parts, trignometric substitution, partial fractions, and improper integrals. Optional topics include vector analysis, developed to study lines, planes and surfaces in 3-dimensional space and/or advanced problem solving techniques used in major mathematics contests. The student develops ideas from analysis throughout AP Calculus BC. The course prepares the student for the BC level Advanced Placement Exam in Calculus and as a result includes an extensive review of relevant topics. By the time the student takes this course, he/she has already met and exceeded the standards set forth by the National Council of Teachers of Mathematics (NCTM), the State of New Mexico Mathematics Standards, and the Albuquerque Public Schools (APS) District Mathematics Standards. Therefore, the performance standards represented in this course can be aligned to the strands “Topics for Further Study” recommended by the State Department of New Mexico.

AP HONORS CALCULUS BC 17.3.12 1 – 7. The student studies how drug dosage is established by researching nasal allergy sprays. Based on the research he/she determines recommended dose rates for a “new” nasal allergy spray. The student creates data, analyzes the data and prepares a brief report including tables and graphs to support answers. Based on research the student: Determines an amount of his/her “new” drug in the person’s body necessary for the drug to be effective but safe (i.e., 50 µg to 80 µg). Gives the amount of drug remaining in the body over a specific time period (i.e., 80% of what it was at the beginning of a 6 hour period). Determines the amount of drug delivered by each puff. (i.e., 7 µg). Writes a geometric series for the amount of drug remaining in the person’s system after n puffs assuming a person uses one puff of the spray each given time period. States when the amount in the person’s system exceeds the given amount necessary to be effective. Determines if the amount would ever exceed the amount necessary to be safe. Examines the effects of using two, three or four puffs each time period. In each case determines when first effective and when, if ever, beyond safe levels. Gives evidence to determine if several puffs of the spray could be taken twice a day and have the levels stay effective and safe. Gives evidence to determine if several puffs of the spray could be taken once a day and have the levels stay effective and safe. Reports on possible effects to the patient if not taken as prescribed. completion of all required components use of technology problem solving strategies Albuquerque Public Schools 03/04 GRADE 9 - 12 PERFORMANCE STANDARDS ILLUSTRATIONS AP HONORS CALCULUS BC 17.4.12 effective communication connections multiple representations Albuquerque Public Schools 03/04 STRAND II: FUNCTIONS, GRAPHS, AND LIMITS CONTENT STANDARD: The students uses geometric, numeric and analytic information about curves.
