Question

What is linear and non linear differential equations?

Answer 1

So x is linear but x2 is non-linear. Also any function like cos(x) is non-linear. In math and physics, linear generally means "simple" and non-linear means "complicated". ... In a differential equation, when the variables and their derivatives are only multiplied by constants, then the equation is linear.

Answer 2

liner equation: are does equations in which if an equation is represent on a graph paper it forms a straight line like.
$2x + 4x + 8 = 0$
