  2. AP Calculus - Wikipedia

    It can be seen from the tables that the pass rate (score of 3 or higher) of AP Calculus BC is higher than AP Calculus AB. It can also be noted that about 1/3 as many take the BC exam as take the AB exam. A possible explanation for the higher scores on BC is that students who take AP Calculus BC are more prepared and advanced in math.

  3. Second partial derivative test - Wikipedia

    en.wikipedia.org/wiki/Second_partial_derivative_test

    In cases 1 and 2, the requirement that f xx f yy − f xy 2 is positive at (x, y) implies that f xx and f yy have the same sign there. Therefore, the second condition, that f xx be greater (or less) than zero, could equivalently be that f yy or tr( H ) = f xx + f yy be greater (or less) than zero at that point.

    AP Physics 1: Algebra-Based and AP Physics 2: Algebra-Based [52] Fluids, which used to be Unit 1 in AP Physics 2, will become Unit 8 in AP Physics 1. The format of both exams will change in the same way: The number of MCQs will go down from 50 to 40, and the time for the section will go down from 90 minutes to 80 minutes.

    Advanced Placement (AP) examinations are exams offered in United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...

    en.wikipedia.org/wiki/Partial_derivative

    Partial derivatives appear in any calculus-based optimization problem with more than one choice variable. For example, in economics a firm may wish to maximize profit π( x , y ) with respect to the choice of the quantities x and y of two different types of output.

    From January 2008 to December 2012, if you bought shares in companies when Richard Kovacevich joined the board, and sold them when he left, you would have a -4.5 percent return on your investment, compared to a -2.8 percent return from the S&P 500.

  9. Integration by parts - Wikipedia

    en.wikipedia.org/wiki/Integration_by_parts

    Integration by parts can be extended to functions of several variables by applying a version of the fundamental theorem of calculus to an appropriate product rule. There are several such pairings possible in multivariate calculus, involving a scalar-valued function u and vector-valued function (vector field) V. [7]
