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 ...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) ( ± ∞).In the previous section we saw that there is a large class of functions that allows us to use. lim x → af(x) = f(a) to compute limits.

Here is a graph of the Heaviside function. Heaviside functions are often called step functions. Here is some alternate notation for Heaviside functions. uc(t) = u(t − c) = H(t − c) We can think of the Heaviside function as a switch that is off until t = c at which point it turns on and takes a value of 1. Paul Gauguin, one of the most influential painters of the 19th century, is renowned for his vibrant and exotic depictions of Tahiti. Tahiti is known for its awe-inspiring natural b...An alternating series is any series, ∑an ∑ a n, for which the series terms can be written in one of the following two forms. an = (−1)nbn bn ≥ 0 an = (−1)n+1bn bn ≥ 0 a n = ( − 1) n b n b n ≥ 0 a n = ( − 1) n + 1 b n b n ≥ 0.

So, similar to the binomial theorem except that it’s an infinite series and we must have |x| < 1 | x | < 1 in order to get convergence. Let’s check out an example of this. In this section we will give the Binomial Theorem and illustrate how it can be used to quickly expand terms in the form (a+b)^n when n is an integer.a(b +c) = ab +ac. In factoring out the greatest common factor we do this in reverse. We notice that each term has an a in it and so we “factor” it out using the distributive law in reverse as follows, ab +ac = a(b+c) Let’s take a look at some examples. Example 1 Factor out the greatest common factor from each of the following polynomials.So, the sequence converges for r = 1 and in this case its limit is 1. Case 3 : 0 < r < 1. We know from Calculus I that lim x → ∞rx = 0 if 0 < r < 1 and so by Theorem 1 above we also know that lim n → ∞rn = 0 and so the sequence converges if 0 < r < 1 and in this case its limit is zero. Case 4 : r = 0.Nov 16, 2022 · This method is often called the method of disks or the method of rings. Let’s do an example.

In other words, temperature will only vary in \(x\) and we can hence consider the bar to be a 1-D bar. Note that with this assumption the actual shape of the cross section (i.e. circular, rectangular, etc.) doesn’t matter. Note that the 1-D assumption is actually not all that bad of an assumption as it might seem at first glance.To determine a condition that must be true in order for a Taylor series to exist for a function let’s first define the nth degree Taylor polynomial of f(x) as, Tn(x) = n ∑ i = 0f ( i) (a) i! (x − a)i. Note that this really is a polynomial of degree at most n.In this section we look at integrals that involve trig functions.

    Parallel concurrent processing | Because the binormal vector is defined to be the cross product of the unit tangent and unit normal vector we then know that the binormal vector is orthogonal to both the tangent vector and the normal vector. Example 3 Find the normal and binormal vectors for →r (t) = t,3sint,3cost r → ( t) = t, 3 sin t, 3 cos t . Show Solution. In this ...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 anyone wanting to learn Linear Algebra or needing a refresher. These notes do assume that the reader has a good working knowledge of basic Algebra. This set...

    Food riots | Nov 16, 2022 · Divergence Theorem. Let E E be a simple solid region and S S is the boundary surface of E E with positive orientation. Let →F F → be a vector field whose components have continuous first order partial derivatives. Then, ∬ S →F ⋅ d→S = ∭ E div →F dV ∬ S F → ⋅ d S → = ∭ E div F → d V. Let’s see an example of how to ... Laplace’s equation in terms of polar coordinates is, ∇2u = 1 r ∂ ∂r (r ∂u ∂r) + 1 r2 ∂2u ∂θ2 ∇ 2 u = 1 r ∂ ∂ r ( r ∂ u ∂ r) + 1 r 2 ∂ 2 u ∂ θ 2. Okay, this is a lot more complicated than the Cartesian form of Laplace’s equation and it will add in a few complexities to the solution process, but it isn’t as bad ......

Case 3 : 0 < r < 1. We know from Calculus I that lim x → ∞rx = 0 if 0 < r < 1 and so by Theorem 1 above we also know that lim n → ∞rn = 0 and so the sequence converges if 0 < r < 1 and in this case its limit is zero. Case 4 : r = 0....
