## Description

This AP course takes you through the concept of integration and various methods of integration. Integration can be used to find areas, volumes and other useful things. It is the way of adding parts to find the whole. Integration can be used to solve two essentially different types of problems. The first type are problems where the derivative of a function, its rate of change or the slope of its graph, is known. In solving such problems, it is required that the process of differentiation is reversed. This reverse process is known as antidifferentiation (integration) or finding an indefinite integral. The second type are problems involving adding up a very large number of very small quantities. This process leads to the definition of the definite integral and its properties. This course illustrates how to solve for the average value of a function on an interval as well as the mean value theorem for integrals.

If you want to learn about the first and second parts of the fundamental theorem of integral calculus, enroll today. The material covers in detail power rules and basic rules to assist in integration. Most expressions in calculus are given in a format that doesn't allow an immediate reversal for the process of differentiation. Therefore, additional methods must be developed. One option is known as u-substitution. Let’s assume you are asked to break a broomstick and a bunch of broomsticks respectively. Which will be easier to do? Of course, the single broomstick! The process of integration goes from the easier aspect to the more difficult aspect. Knowing how to differentiate the six basic trigonometric functions streamlines the process of finding many integrals involving trigonometric expressions since finding the integral is a process of anti-differentiation. The course explores some of the more frequently used trigonometric integrals as well as the trig substitutions useful in integrating certain binomials.

Furthermore, in integration, we have the derivative of a function and need to find the original function. In order to use the method of integration by partial fractions, we must first decompose a fractional integral into the sum of simpler fractions. You will learn about partial fraction decomposition, first-order differential equations and how to satisfy initial conditions when solving differential equations. The integration by parts is a technique that is frequently useful for integrating functions that are described by the product of two functions. This course illustrates other integration methods: integration of inverse trigonometric functions and hyperbolic functions. You will be able to solve for arc length, the surface of revolution and determine the volume of solid with known cross-section. Calculus can be applied to equations expressed in polar coordinates. These range from finding the area using polar coordinates, finding the polar coordinates of the point with Cartesian coordinates and finding the Cartesian equation of a curve. The learning content in this course is crucial for math students who want to pass the AP Calculus exam.
