![]() ![]() ![]() If equations contain only linear terms of the independent variables – that is, only constants multiplied by each variable – and constants, then the equation is linear If the equation contains any terms such as x2, cos(x), ex, etc., then the equation is non-linear Consider these two linear equations: Engineering Computation: An Introduction Using MATLAB and ExcelĪre there values of x and y that fit both equations? That is, are there values of x and y that simultaneously satisfy both equations? For two equations, it is easy to find the solution by substitution: Write the second equation as: Engineering Computation: An Introduction Using MATLAB and Excel Permission required for reproduction or display.
