It is commonly used to take a randomly generated number and reduce that number to a random number on a smaller range, and it can also quickly tell you if one number is a factor of another. In most versions of Mathcad, comments appear in Arial font and Mathcad statements such as "given" appear Times New Roman. where is a Lerch transcendent. The context of the equation should help you identify which quantity is meant. De Broglie’s equation allows one to determine the wavelength of electromagnetic radiation given the momentum of its quanta. Take the wave equation (formula): y(t) = A × (sin ω t + φ) + C. For instance, A=5 will produce a wave which goes from 0 to 5; P=10 will produce a wave with a period of 20. POISSON_MPI, a C program which computes a solution to the Poisson equation in a rectangle, using the Jacobi iteration to solve the linear system, and MPI to carry out the Jacobi iteration in parallel.
