In this section we are going to take a look at differential equations in the form, y′ +p(x)y = q(x)yn y ′ + p ( x) y = q ( x) y n. where p(x) p ( x) and q(x) q ( x) are continuous functions on the interval we’re working on and n n is a real number. Differential equations in this form are ...

Nov 16, 2022 · We can get the units of the derivative by recalling that, r ′ = dr dt. The units of the derivative will be the units of the numerator (cm in the previous example) divided by the units of the denominator (min in the previous example). Let’s work some more examples. Example 2 A 15 foot ladder is resting against the wall. Apr 5, 2019 · Laplace transforms comes into its own when the forcing function in the differential equation starts getting more complicated. In the previous chapter we looked only at nonhomogeneous differential equations in which g(t) g ( t) was a fairly simple continuous function. In this chapter we will start looking at g(t) g ( t) ’s that are not continuous.

This is a fairly important idea and we will be doing quite a bit of this kind of thing in Calculus III.

Complex Conjugate. The first one we’ll look at is the complex conjugate, (or just the conjugate).Given the complex number z = a + bi the complex conjugate is denoted by ¯ z and is defined to be, ¯ z = a − bi. In other words, we just switch the sign on the imaginary part of the number. Here are some basic facts about conjugates.In this chapter we will introduce a new kind of integral : Line Integrals. With Line Integrals we will be integrating functions of two or more variables where the independent variables now are defined by curves rather than regions as with double and triple integrals. We will also investigate conservative vector fields and discuss Green’s ...Nov 16, 2022 · In this section we introduce the method of variation of parameters to find particular solutions to nonhomogeneous differential equation. We give a detailed examination of the method as well as derive a formula that can be used to find particular solutions. Nov 16, 2022 · First, when doing a substitution remember that when the substitution is done all the x x ’s in the integral (or whatever variable is being used for that particular integral) should all be substituted away. This includes the x x in the dx d x. After the substitution only u u ’s should be left in the integral.

Given the two Laplace transforms F(s) and G(s) then. L − 1{aF(s) + bG(s)} = aL − 1{F(s)} + bL − 1{G(s)} for any constants a and b. So, we take the inverse transform of the individual transforms, put any constants back in and then add or subtract the results back up. Let’s take a look at a couple of fairly simple inverse transforms.

Nov 16, 2022 · In the section we introduce the concept of directional derivatives. With directional derivatives we can now ask how a function is changing if we allow all the independent variables to change rather than holding all but one constant as we had to do with partial derivatives. In this section we want do take a look at triple integrals done completely in Cylindrical Coordinates. Recall that cylindrical coordinates are really nothing more than an extension of polar coordinates into three dimensions. The following are the conversion formulas for cylindrical coordinates. x =rcosθ y = rsinθ z = z x = r cos θ y = r sin ...First, we need to recall just how spherical coordinates are defined. The following sketch shows the relationship between the Cartesian and spherical coordinate systems.

We can also give a strict mathematical/formula definition for absolute value. It is, |p| = {p if p ≥ 0 −p if p < 0 | p | = { p if p ≥ 0 − p if p < 0. This tells us to look at the sign of p p and if it’s positive we just drop the absolute value bar. If p p is negative we drop the absolute value bars and then put in a negative in front ...Paul's Online Notes Home / Calculus III / Multiple Integrals / Triple Integrals. Prev. Section.

You appear to be on a device with a "narrow" screen width (i.e. you are probably on a mobile phone).Section 4.1 : Rates of Change. The purpose of this section is to remind us of one of the more important applications of derivatives. That is the fact that f ′(x) f ′ ( x) represents the rate of change of f (x) f ( x). This is an application that we repeatedly saw in the previous chapter. Almost every section in the previous chapter ...Surface Integrals – In this section we introduce the idea of a surface integral. With surface integrals we will be integrating over the surface of a solid. In other words, the variables will always be on the surface of the solid and will never come from inside the solid itself. Also, in this section we will be working with the first kind of ...Here are my online notes for my Linear Algebra course that I teach here at Lamar University. Despite the fact that these are my “class notes”, they should be accessible to …Nov 16, 2022 · W =F d W = F d. However, most forces are not constant and will depend upon where exactly the force is acting. So, let’s suppose that the force at any x x is given by F (x) F ( x). Then the work done by the force in moving an object from x = a x = a to x = b x = b is given by, W =∫ b a F (x) dx W = ∫ a b F ( x) d x. In this section we are going to start talking about power series. A power series about a, or just power series, is any series that can be written in the form, ∞ ∑ n=0cn(x −a)n ∑ n = 0 ∞ c n ( x − a) n. where a a and cn c n are numbers. The cn c n ’s are often called the coefficients of the series.

Section 14.5 : Lagrange Multipliers. In the previous section we optimized (i.e. found the absolute extrema) a function on a region that contained its boundary.Finding potential optimal points in the interior of the region isn’t too bad in general, all that we needed to do was find the critical points and plug them into the function.Stokes’ Theorem.

(The information below is from Paul Foerster, Alamo Heights High School, San Antonio).In terms of our new function the surface is then given by the equation f (x,y,z) = 0 f ( x, y, z) = 0. Now, recall that ∇f ∇ f will be orthogonal (or normal) to the surface given by f (x,y,z) = 0 f ( x, y, z) = 0. This means that we have a normal vector to the surface. The only potential problem is that it might not be a unit normal vector.Section 7.10 : Approximating Definite Integrals.

L’Hospital’s Rule works great on the two indeterminate forms 0/0 and ±∞/±∞ ± ∞ / ± ∞. However, there are many more indeterminate forms out there as we saw earlier. Let’s take a look at some of those and see how we deal with those kinds of indeterminate forms. We’ll start with the indeterminate form (0)(±∞) ( 0) ( ± ∞).Section 4.3 : Minimum and Maximum Values. Many of our applications in this chapter will revolve around minimum and maximum values of a function. While we can all visualize the minimum and maximum values of a function we want to be a little more specific in our work here.
