FORM THREE MATHEMATICS NOTES| MATHEMATICS SOLVING
Topic 5.0: Sequence and series
Topic 7.0: The earth as sphere
Topic 1.0: Relation
This topic introduces the concept of how elements from one set can be connected to elements of another set. It covers ordered pairs, Cartesian products, and how to represent relations using arrow diagrams, tables, and graphs. Understanding relations helps students build the foundation for functions and more advanced algebra later in their studies.
Topic 2.0: Function
A function is a special kind of relation where each input has exactly one output. In this topic, students learn about different types of functions (linear, quadratic), how to evaluate functions, and how to draw their graphs. Functions are useful in real-life situations, such as calculating profit, population growth, or speed over time.
Topic 3.0: Statistics
Statistics teaches how to collect, organize, present, and interpret data. Students learn about frequency tables, bar charts, histograms, and pie charts. Measures of central tendency like mean, median, and mode are also introduced. This topic is important for making sense of data in daily life, such as analyzing test results or survey findings.
Topic 4.0: Rate and Variation
This topic focuses on the comparison of quantities. It includes concepts such as speed, density, and work rate. Students also explore direct and inverse variation. These ideas are very practical, appearing in everyday calculations like fuel consumption, travel time, and recipe adjustments.
Topic 5.0: Sequence and Series
Here, students discover how numbers can follow a particular order or pattern. They study arithmetic and geometric sequences, find the nth term, and calculate the sum of series. Recognizing patterns in numbers helps students in problem-solving and logical thinking.
Topic 6.0: Circle
This topic explores the geometry of circles. Students learn about parts of a circle—radius, diameter, chord, arc, and sector—and how to calculate perimeter and area. It also covers angle properties in a circle, which is key in solving many geometrical problems in exams and real-life design projects.
Topic 7.0: The Earth as a Sphere
This is one of the most exciting topics, where students apply mathematical concepts to the shape of the Earth. It includes concepts like latitude, longitude, great circles, and calculation of distances using degrees. This topic links math with geography and navigation.
Topic 8.0: Account
In this topic, students learn basic bookkeeping and financial mathematics. It includes income, expenditure, profit, loss, simple interest, and discount. These skills are practical and vital for managing money wisely, whether in personal life or business.
