What is a non linear equation.?

Answer 1

A non-linear equation is an equation in which the variables do not have a linear relationship, meaning they cannot be expressed as a straight line when graphed. Instead, non-linear equations may involve polynomial, exponential, logarithmic, or trigonometric functions, resulting in curves or more complex shapes. Examples include quadratic equations, such as (y = ax^2 + bx + c), and exponential equations, like (y = a \cdot e^{bx}). These equations often have multiple solutions or no solutions at all, unlike linear equations which typically have a single solution.
