(4) (a) Give an example of a relation (different to those in question 1) which is symmetric and transitive but not reflexive. (b) Identify the problem with the following proof: Let R be a relation on a set S, and suppose that R is symmetric and transitive. Since the relation is symmetric, we know that a bb~a, and then it follows from transitivity that a ~b and b ~ a → a ~ a. Therefore any symmetric and transitive relation...

HW3.2: Problem 1 Previous Problem Problem List Next Problem (1 point) Given a second order linear homogeneous differential equation a2(x)y" + ai (x)y' + ao (x)y0 we know that a fundamental set for this ODE consists of a pair linearly independent solutions yi, y2. But there are times when only one function, call it y, is available and we would like to find a second linearly independent solution. We can find 2 using the method of reduction of order. First,...

(1 point) In this problem you will solve the differential equation or @() (1) Since P(a) 0 are not analytic at and 2() is a singular point of the differential equation. Using Frobenius' Theorem, we must check that are both analytic a # 0. Since #P 2 and #2e(z) are analytic a # 0-0 is a regular singular point for the differential equation 28x2y® + 22,23, + 4y 0 From the result ol Frobenius Theorem, we may assume that 2822y"...

Item 1 In the case below, the original source material is given along with a sample of student work. Determine the type of plagiarism by clicking the appropriate radio button. Original Source Material Student Version While solitary negative reactions or unjustified suggestions for change have the potential to dissipate discourse rather than build it, the pattern analysis shows that the anonymous condition seemed to provide a safe explorative space for learners to try out more reasons for their multiple solutions....
