Mathematics — WAEC & JAMB

Concise explanations, high-yield topics and worked examples to help you score higher.

Quick Overview

This guide focuses on algebra, trigonometry, geometry, coordinate geometry and calculus basics asked in Nigerian exams.

Key Topics

  • Algebra: equations, inequalities, sequences
  • Trigonometry: identities, angles, solving triangles
  • Geometry: mensuration, circles, polygons
  • Coordinate geometry: lines, circles, intersections

Formula Sheet (cheat-sheet)

  • Quadratic formula: x = [-b ± sqrt(b²-4ac)] / (2a)
  • Sine rule / Cosine rule
  • Area (triangle): 1/2 * base * height

Worked Example

Q: Solve for x: 2x² - 3x - 5 = 0

A: Using quadratic formula: x = [3 ± sqrt(9 + 40)] / 4 = [3 ± 7] / 4 → x = 2.5 or x = -1
