Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

how to papers topics - May 26,  · If we use the conditions y(0) y (0) and y(2π) y (2 π) the only way we’ll ever get a solution to the boundary value problem is if we have, y(0) = a y(2π) = a y (0) = a y (2 π) = a for any value of a a. Also, note that if we do have these boundary conditions we’ll in fact get infinitely many solutions. A boundary value problem (BVP) speci es values or equations for solution components at more than one x. Unlike IVPs, a boundary value problem may not have a solution, or may have a nite number, or may have in nitely many. Because of this, programs for solving BVPs require users to provide a guess for the solution desired. Of-File Size: KB. If these boundary conditions and σ do not depend on time, the temperature within the rod ultimately settles to the solution of the steady-state equation: d 2 T d x 2 (x) = b (x), b (x) = − σ (x) / α. In the examples below, we solve this equation with some common boundary conditions. harvard dissertation database

free essay on line - 5. Boundary Value Problems (using separation of variables). Seven steps of the approach of separation of Variables: 1) Separate the variables: (by writing e.g. u(x,t) = X(x)T(t) etc.. 2) Find the ODE for each “variable”. 3) Determine homogenous boundary values to stet up a Sturm- Liouville problem. 4) Find the eigenvalues and eigenfunctions. The shooting method works by considering the boundary conditions as a multivariate function of initial conditions at some point, reducing the boundary value problem to finding the initial conditions that give a root. The advantage of the shooting method is that it takes advantage of the speed and adaptivity of methods for initial value problems. Boundary Value Problems • Auxiliary conditions are specified at the boundaries (not just a one point like in initial value problems) T 0 T∞ T 1 T(x) T 0 T 1 x x l Two Methods: Shooting Method Finite Difference Method conditions are specified at different values of the independent variable! students persuasive essays
