# What to Review for Calc 2?

If you’re taking Calc 2, you know that there’s a lot to review. But what should you focus on? Here’s a list of the most important topics to review.

## The Basics of Calc 2

There are a few things that you should know before taking on Calc 2. This will be a review of the basics of calculus and some of the concepts that you should know before taking the course.

Calculus is the study of change, in the most general sense. It is used to describe and understand the world around us. In math, we use calculus to find things like velocity and acceleration, which are both measures of change.

The two main branches of calculus are differential calculus and integral calculus. Differential calculus deals with rates of change, while integral calculus deals with the accumulation of change. These two branches are connected by the fundamental theorem of calculus, which states that differentiation is the reverse process of integration.

Calc 2 is a course that builds on the foundations you learned in Calc 1. In Calc 2, you will learn about more advanced topics such as integrals, derivatives, and limits. You will also learn about how to apply these concepts to solving real-world problems. By the end of the course, you should be able to integrate different functions and understand their applications in physics and engineering.

## Derivatives

The derivative of a function at a point is the slope of the tangent line to that function at that specific point. It can be thought of as an “infinitesimal” change in the function, corresponding to an “infinitesimal” change in its argument. The word derivative comes from Latin: derivare meaning “to derive, to get”.

## Integrals

To start off, you should know how to find anti-derivatives/indefinite integrals. This involves understanding how to use basic integration rules, such as the power rule, the constant multiple rule, the sum/difference rule, and the substitution rule. You should also be proficient in using partial fractions to decompose integrands. Furthermore, you should be able to use trigonometric identities to simplify integrands that contain trig functions. Lastly, it is also important to know how to work with piecewise functions when finding integrals.

In addition to being able to find anti-derivatives/indefinite integrals, you should also be able to calculate definite integrals. This includes knowing how to use the properties of definite integrals (such as the fact that the definite integral of a continuous function is always zero), as well as being familiar with the different methods of evaluating definite integrals (such as numerical integration and integration by parts).

## Applications of Derivatives

Learning objectives After watching this module, students should be able to:
– Understand the meaning of a derivative
– Recognize derivatives in mathematical and real-world contexts
– Understand the connection between derivatives and slopes of tangent lines
– Calculate derivatives using limit definitions and slope formulas
– Use derivatives to solve rate of change and optimization problems

In this module, we’ll be reviewing some applications of derivatives that you might see on the Calc 2 final exam. We’ll start by reviewing what a derivative is and what it means in both mathematical and real-world contexts. Next, we’ll review how to calculate derivatives using limit definitions and slope formulas. Finally, we’ll use derivatives to solve rate of change and optimization problems.

## Applications of Integrals

Integrals are used in a variety of applications, including:

-Calculating the area under a curve
-Calculating the volume of a solid of revolution
-Calculating the length of a curve
-Modeling displacement, velocity, and acceleration
-Modeling population dynamics
– solving differential equations

## Series

In a series, each term is related to the one before or after it by a fixed rule. The sum of the terms in a series is called a series expansion. There are two types of series that you’ll need to know for calculus: arithmetic and geometric.

Arithmetic Series
An arithmetic series is a series in which each term is obtained by adding a constant, d, to the previous term. The general form of an arithmetic series is:

a, a+d, a+2d, … , a+(n-1)d

The common difference, d, can be positive or negative. If d < 0, then the terms will decrease; if d > 0, the terms will increase.

Geometric Series
A geometric series is a series in which each term is obtained by multiplying the previous term by a constant, r. The general form of a geometric series is:

a, ar, ar^2,… ,ar^(n-1)

## Parametric Equations and Polar Coordinates

In Calculus 2, you learned about Polar Coordinates and Parametric Equations. These concepts are intertwined and together can be used to model many real world situations. Here is a review of the main topics covered in this unit.

Polar Coordinates
Polar coordinates are a way of representing points in a plane using a length and an angle. The angle is measured from the positive x-axis and the length is the distance from the origin (0,0).

Parametric Equations
Parametric equations are equations that express a point in terms of a parameter. For example, the point (x,y) can be represented parametrically as (x(t), y(t)). The parameter t can be thought of as time or any other variable that you want to use to express the point.

## Conic Sections

There are four basic types of conic sections: circles, ellipses, hyperbolas, and parabolas. Each type is formed by the intersection of a plane and a double cone. The circle is the intersection of a plane that is perpendicular to the double cone’s axis. An ellipse occurs when the plane intersects the double cone at an angle that is less than perpendicular. A hyperbola occurs when the plane intersects the double cone at an angle that is greater than perpendicular. A parabola occurs when the plane intersects the double cone parallel to one of its generators.

## Vectors

In mathematics, a vector is an object that has both a magnitude and a direction. Vectors are often used in physics and engineering applications, and their mathematical properties allow them to be used in navigation, mechanics, and electricity. There are three types of vectors: magnitude vectors, direction vectors, and displacement vectors. Magnitude vector is the shortest vector between two points, while direction vector points from one point to another. Displacement vector is created when the direction vector is divided by the magnitude vector.

## 10) 3-Dimensional Coordinates

Three-dimensional (3D) coordinates are a good way to represent points in space. A point in 3D space can be represented by its x-, y-, and z-coordinates. The x-coordinate is the point’s distance from the yz-plane, the y-coordinate is the point’s distance from the xz-plane, and the z-coordinate is the point’s distance from thexy-plane.
