Quantum equation predicts universe has no beginning February 9, by Lisa Zyga, Phys. Note on the left the dramatic expansion not to scale occurring in the inflationary epoch, and at the center the expansion acceleration. The scheme is decorated with WMAP images on the left and with the representation of stars at the appropriate level of development. The model may also account for dark matter and dark energy, resolving multiple problems at once.
Suyeon Khim contributed A Diophantine equation is a polynomial equation whose solutions are restricted to integers. These types of equations are named after the ancient Greek mathematician Diophantus. A linear Diophantine equation is a first-degree equation of this type.
Diophantine equations are important when a problem requires a solution in whole amounts.
How many ways are there to make from only nickels and quarters? Let be the number of nickels and let be the number of quarters. Then a solution to this problem would satisfy the equation However, this is a bit different from simply solving an equation because there is more than one solution to account for; the solutions are restricted by the fact that they must be non-negative integers.
The study of problems that require integer solutions is often referred to as Diophantine analysis. Although the practical applications of Diophantine analysis have been somewhat limited in the past, this kind of analysis has become much more important in the digital age.
Diophantine analysis is very important in the study of public-key cryptographyfor example.Linear Equations – In this section we solve linear first order differential equations, i.e. differential equations in the form \(y' + p(t) y = g(t)\).
We give an in depth overview of the process used to solve this type of differential equation as well as a derivation of the formula needed for the integrating factor used in the solution process.

Flow velocity. The solution of the Navier–Stokes equations is a flow regardbouddhiste.com is a field, since it is defined at every point in a region of space and an interval of time. Parametric Equations in the Graphing Calculator.
We can graph the set of parametric equations above by using a graphing calculator. First change the MODE from FUNCTION to PARAMETRIC, and enter the equations for X and Y in “Y =”..
For the WINDOW, you can put in the min and max values for \(t\), and also the min and max values for \(x\) and \(y\) if you want to. (Note that with non-linear equations, there will most likely be more than one intersection; an example of how to get more than one solution via the Graphing Calculator can be found in the Exponents and Radicals in Algebra section.) Solving Systems with Substitution.
One equation of my system will be x+y=1 Now in order to satisfy (ii) My second equations need to not be a multiple of the first. If I used 2x+2y=2, it would share, not only (4, -3), but every solution.
