Non-Linear Equation

A non-linear equation contains a term whose variable is not simply to the first power, for example $x^{2}$, $xy$, or $\frac{1}{x}$. Its graph is a curve rather than a straight line.

In this chapter it is paired with a linear equation and solved simultaneously by substitution.

You meet Non-Linear Equation in the Systems of Equations chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Non-Linear Equation means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Non-Linear Equation (EN) · Persamaan Tak Linear (BM) · 非线性方程 (中文)
