Gradient Function

The gradient function is another name for the first derivative $f'(x)$, because it gives the gradient of the curve at any value of $x$. Substituting a particular $x$ into it returns the slope of the tangent there, which tells us whether the curve is rising or falling.

You meet Gradient Function in the Differentiation 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 Gradient Function 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: Gradient Function (EN) · Fungsi Kecerunan (BM) · 斜率函数 (中文)
