Abstract: Simultaneous nonlinear differential equations of growth of two variables x and y with time can be readily solved graphically by a method in which two directrices are used in the ...

Simultaneous equations are two or more equations with two or more variables. They are simultaneous because they can be solved to give values for the variables that are equal in each equation. This is ...

Be careful to note what a GCSE question is asking. If it states ‘solve algebraically’ then you must do so. To find solutions from graphs, look for the point where the two graphs cross one another.

Abstract: A simple and efficient graphical selective harmonic elimination method has been developed in this paper using which multiple harmonics can be simultaneously reduced even with two switchings ...

This article considers the problem of making simultaneous probability statements in multivariate inferential problems based on samples from a posterior distribution. The calculation of simultaneous ...
