SSS 2 THIRD TERM MATHEMATICS WEEK 4 Topic: PROBABILITY Introduction Probability is the measure of the likeliness that an event will occur. Probability is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty). The higher the probability of an event, the more certain we are that the event

JSS 2 Mathematics Second Term Week 3 Topic: FACTORS, FACTORIZATION, FRACTIONS FACTORIZATION OF BINOMIALS Binomials are expressions with only two terms being added. 2×2 – 4x is an example of a binomial. (You can say that a negative 4x is being added to 2×2.) First, factor out the GCF, 2x. You’re left with 2x (x –

SSS 2 SECOND TERM MATHEMATICS WEEK SEVEN Topic: BEARING AND DISTANCES Bearing can be defined as the clockwise angular movement between two distant places. Rules for Solving Bearing and Distances 1. Taking reading in bearing starts from the North Pole in clockwise direction and ends also at the North Pole. I.e. North – North Pole reading.

If you are a student of Mathematics or Further Mathematics, then you cannot help but come across trigonometric identities – Sine, Cosine and Tangent. So what should you do when they are presented in mathematical problems? Just hold on, dear student, live and learn. Because sine, cosine, and tangent are functions (trig functions), they can

JSS 3 Mathematics Second Term Week 5 Topic: PROPORTION – DIRECT, INVERSE AND RECIPROCALS Direct Proportion If two quantities are in direct proportion, as one increases, the other increases by the same percentage. If y is directly proportional to x, this can be written as y ∝x A simple example of two things that are

JSS 3 Mathematics Second Term Week 8 Topic: EVERYDAY STATISTICS Measures of Central tendency Introduction A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. As such, measures of central tendency are sometimes called measures of central location.

JSS 3 Mathematics Second Term Week 7 Topic: SINE AND COSINE OF ANGLES The sine (abbreviated “sin“) and cosine (“cos“) are the two most prominent trigonometric functions. All other trig functions can be expressed in terms of them. In fact, the sine and cosine functions are closely related and can be expressed in terms of each other. Definition
