nonlinear equations definition math example. This is nonlinear because although it is a polynomial its highest exponent is 2 not 1. An equation that is not a straight line when it is graphed.
Has degree of two or more. Note as well that the discussion here does not cover all the possible solution methods for nonlinear systems. Navier-Stokes equation and Eulers equation in fluid dynamics Einsteins field equations of general relativity are well known nonlinear partial differential equations.
Y cos x lots more.
For example y d y d x is non-linear. Parabolic functions in business measure a companys marginal output by comparing units per employee. For example 5x 2 1 is Linear equation in one variable. S i n y x 7 5 c o s x is non-linear.
