JC H2 Maths Tuition | Riemann Sum Explained – From Rectangles to Integration (Exam Question)

In this JC H2 Maths tuition video, we walk through an A-Level exam-style question on Riemann sums, focusing on how the area under a curve can be estimated using rectangular strips. You will learn: How Riemann sums approximate the area under a curve The difference between using left-end points and right-end points How to observe which rectangles overestimate or underestimate the area Why increasing the number of rectangles improves accuracy The key idea behind the limit of Riemann sums becoming integration Most importantly, we explain the core concept examiners expect: 👉 when the width of each rectangle approaches zero, the sum of their areas tends towards the definite integral of the function. This lesson is especially useful for JC1 & JC2 students preparing for H2 Mathematics, helping you connect graphical intuition with formal calculus techniques used in exams. ABOUT JC H2 MATH TUITION CLASSES https://mathacademy.sg/courses/jc-mat... All JC Classes are taught by Mr Ian Ang. He holds a First Class Honours in Pure Mathematics from NUS. This is awarded only to the top 5% of the cohort at NUS, with little to no Singaporeans achieving this feat in a highly competitive Mathematics cohort. He has also achieved a perfect L1R5 of 6 points at the O levels, scoring A in all Math subjects (E Math, A Math, H2 Math, Further Math) at all national exams. Mr Ang’s excellence in Mathematics throughout his academic years is not by chance. His exceptional ability to summarize and breakdown the different techniques in solving Math questions has propelled him and his students to achieve incredible results at the national exams. #h2math #h2mathtuition #jch2mathematics #jcmathematics #jcmathtuition #juniorcollege #singaporemath #singapore #alevel #alevelstudents #alevelmath #alevelmaths #mathematics #maths #tuition #tuitioncentre #sgtuition #JCH2Math #H2MathTutorial #SGMath #MathAcademy #integration
