In addition to blogging about AP Calculus, Oakland resident Chris Wirick has played the oboe in Beijing and Berlin, studied math and cognitive science (the other CS) at Cal Berkeley, and can’t stop gardening, cooking and eating new foods.
Computing the Definite Integral of a Polynomial
We want to focus on the definite integral of a polynomial function. These arise very commonly in calculus, so here are detailed solutions to two problems, one multiplechoice and one freeresponse, involving a definite integral of polynomial. FreeResponse Definite Integrals: You will not commonly be asked to evaluate common definite integrals on the freeresponse, […]
AP Calculus: AB Free Response
The free response portion of an AP Exam (also officially known as Section II) is very important, and the AP Calculus AB free response is no different. In fact, the AB free response section is weighed equally with your multiple choice results. It also turns out that the structure of the AB and BC Exams […]
AP Calculus: The Difference between a Graph and a Function?
Did you know that a graph of a function f is not the same as the function itself? It might seem like there is clearly a difference, but sometimes it’s hard to articulate into words. We have spoken about the definition of a function. Simply put, it’s a rule that transforms one real number into […]
AP Calculus: Computing the Antiderivatives of Functions and Polynomials
Warmup: Keeping with the theme of volume of solids of revolution, try this multiple choice question, which should need only understanding of the geometric meaning of the definite integral as a measurement of volume. Question: A solid is generated by revolving the region enclosed by the function , and the lines x =2, x =3, y […]
