Selecting a suitable equation to represent a set of multifactor data that was collected for other purposes in a plant, pilot-plant, or laboratory can be troublesome. If there are k independent ...

Find the gradient and y-intercept for the straight line with equation \(2x + y - 13 = 0\). Rearrange the equation into the form \(y = mx + c\) using the algebraic rules for solving equations.

In this paper, the homotopy perturbation method (HPM) is applied to solve the multipantograph delay equations with variable coefficients. The sufficient conditions are given to assure the convergence ...
