Amplitude
The amplitude of a trigonometric graph is the greatest distance of the curve from its central line, showing how tall the wave is. For , the amplitude is .
It measures the size of the oscillation but does not affect how often the pattern repeats.

Where it appears in Add Math
You meet Amplitude in the Trigonometric Functions 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 Amplitude means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Amplitude (EN) · Amplitud (BM) · 振幅 (中文)
