Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. The approximations [latex]x_0,x_1,x_2, \cdots[/latex] may approach a different root. If the function [latex]f[/latex] has more than one root, it is possible that our approximations do not approach the one for which we are looking, but approach a different root (see Figure 4). This event most often occurs when we do not choose the approximation ...Practice Questions on Fourier Series. 1. Find the Fourier series of the following: (i) x – x 2 for –𝜋 ≤ x ≤ 𝜋. (ii) f (x) = –1 for –𝜋 < x < 0 and f (x) = 1 for 0 ≤ x ≤ 𝜋. 2. For f (x) = x 2 (1 – x 4) find the b n of the Fourier series x ∈ (–l,l). 3. Write the Fourier sine series for f (x) = k in (0, 𝜋).Solve for x (x-5)^2(x+2)<0. Step 1. If any individual factor on the left side of the equation is equal to , the entire expression will be equal to . Step 2.0 if x%2==0 the syntax is value1 if conditionX else value2, what it does is if conditionX is true, it returns value1, otherwise it returns value2. You cannot use it if you want to get the event numbers from the list, you always return value 0 if it is an even number and you miss the else clause. You can achieve it like this:

Example 8.2.2. Let us look at x ′ = y + y2ex, y ′ = x. First let us find the critical points. These are the points where y + y2ex = 0 and x = 0. Simplifying we get 0 = y + y2 = y(y + 1). So the critical points are (0, 0) and (0, − 1),and hence are isolated. Let us compute the Jacobian matrix: [y2ex 1 + 2yex 1 0].3x2 − x − 2 = 0 3 x 2 - x - 2 = 0. Factor by grouping.
