Review Critical Points
Review critical points A critical point is a point where the partial derivatives are both O. In this lecture, we will continue to explore critical points and learn how to actually decide whether a particular point is a minimum, maximum, or sadale point. There are various kinds of critical points. Local minima, local maxima, which are like that, and saddle points which are neither minima nor maxima. And, of course, if you have a real function, then it will be…...

Transitioning Between Rectangular and Polar Coordinates
Example Polar Coordinates To make this more concrete, consider the case in which you want to switch between rectangular and polar coordinates. In rectangular coordinates, you use x and y to locate a point in the plane: in polar coordinates. vow use r. the distance from the origin, and theta, the angle from the x-axis. [Graph] Thus, the change of variables for this equation is x equals r cosine theta and y equals r sine theta. x = r cos…...

L’Hopital’s Rule: Using Derivatives to Evaluate Limits
L'Hopital's Rule L'Hopital's Rule states that if you have the limits of two functions, and the limit of the product of those functions is equal to the ratio of the limits of each function. then the derivative of that product will equal the derivative of that ratio. lim_(x->0) 3x/x=3 lim_(x->0)(x^2 -x)=0 lim_(x->0) [Graph] L'Hopital's Rule lim_(x->a) f(x)/g(x)=lim_(x->a) f'(x)/g'(x) if the limits an indeterminate form (0/0, inf/inf) We will conclude our discussion of limits by revisiting the concept and using derivatives…...

Writing Equations as Dot Products
Writing equations as dot products Here is the question: find a vector v that is perpendicular to 1, comma, one-half, (1, 1/2). Find v perp to (1,12) The answer is we can check if it's perpendicular by taking the dot product. We want the dot product of v1 and v2 to be 0. If we write out this dot product, we get v1 plus one-half of v2. 0=*1,12=v1+12v2 So, there are many possible solutions to this problem. If you pick…...

Solving Chain Rule Problems: Methods and Solutions
Chain Rule Problem Solution To begin, we must first recall that the total differential of z equals the partial derivative of z in the x direction multiplied by dx plus the partial derivative of z in the y direction multiplied by dy. a) dz = z_x dx + z_y dy Now, looking at our formula for z, we see that the partial derivative in the x direction is 2x, and the partial derivative in the y direction is 2y. dz…...

Analytical Approaches to Finding Limits: Factoring, Rationalizing, and Algebraic Techniques
Finding Limits Analytically The limit of a function x approaches 3 as x approaches 3. We will call that x squared. If we graph this, it looks something like this. And there are tick marks, but we will not worry about them. The value 3 is over here and we have a point on the on curve approaching 9 Let f(x) = x2. Then f(3) = 9, so the limit of f(x) as x approaches 3 is also 9. This…...

Level Curves and Partial Derivatives. Contour Plots and Level Curves
Level curves and partial derivatives. Contour plots and level curves The contour plot is another way to look at functions of two variables. It gives a slightly different view of the surface than the standard plot, and it's useful for visualizing regions where the function has extreme values. A contour plot is a way of representing the function of two variables by using a map. The same way that when you walk around, you have actual geographical maps that fit…...

Simplifying Equations for Analysis
Rearranging the formula The equations we have to solve are as follows: <=>{sum_(i=1)^n (X_i^2 a+X_i b-X_iY_i)=0 {sum_(i=1)^n (X_i a+b-y_1)=0 So the first equation can be simplified by looking at the coefficients of a and b. You'll see that there are actually linear equations in a and b, so there's a lot of clutter with all these x's and y's all over the place. Let's simplify the formula by dividing out the factors of two. We can eliminate a and b…...

L’Hopital’s Rule. Example Problem
L'Hopital's Rule. Example Problem lim_(x->0) (cos(3x)-e^4x)/(x^2 -3x) lim_(x->0) (-3sin(3x)-4e^4x)/(2x-3)=-4/-3 =4/3 Let us consider the following example of L'Hopital's rule. If you evaluate the cosine of 0, you get 1. The exponential of 0 is 1, divided by 0 minus 0 - we get 0/0. Factoring probably won't work, since there are no algebraic methods or anything that will help us. We'll use L'Hopital's rule instead. Thus, we take the derivative of the numerator (3sin3x), times 3 because of the chain…...

Calculus: Parallel Lines
Parallel lines Parallel and perpendicular lines are defined as follows: Parallel lines- two or more lines that do not intersect with each other, no matter what distance you move them. Perpendicular lines- two or more lines that intersect at a 90 degree angle. What if we don't have a line that's exactly equal to 0? Rephrasing, instead of x + 1/2 y = 0, what if we had x + 1/2 y = 1? Consider having the line x plus…...

Finding the Rotated Vector: Solving for w in Various Cases
Rotating a Vector Here's the problem: Let v denote a vector that has initial position v1 and final position v2. We know these two numbers. Now suppose we rotate v counterclockwise by an angle theta. The result is a new vector, denoted by w, that also has initial position v1 and final position v2. Let's say that we rotate vector v by an angle theta. If we do this, our new vector becomes w. The problem we are going to…...

Calculus Basics: Limits, Functions, Derivatives, Integrals, and Series
Calculus is the study of change which focuses on limits, functions, derivaties, integrals, and infinite series. There are two main branches of calculus: differential calculus and integral calculus, which are connected by the fundamental theorem of calculus. It was discovered by two different men in the seventeenth century. Gottfried Wilhelm Leibniz – a self taught German mathematician – and Isaac Newton – an English scientist – both developed calculus in the 1680s. Calculus is used in a wide variety of…...

Applying Math to Real Life
I think that many math topics have meaning and relevancy and are dependent on the path one takes in terms of finding real world application. For example, sports is largely dependent on sports. Decisions are made based regarding playing time as well as strategy based on percentages. In baseball, there is a strong use of math. Managers have to make decisions on which pitchers to start and, especially so in games of importance, those decisions are predicated upon statistical reality.…...

Application of Geometric Sequences and Series
A sequence is a set of real numbers. It is a function, which is defined for the positive integers. The value of the function at a given integer is a term of the sequence. The range of a sequence is the collection of terms that make up the sequence. If the sequence only be defined for the positive integers up to a given integer n is called infinite sequences. If a sequence defined only for positive integers up to a…...
