In grade 10 you learnt about vectors in one dimension. Now we will take these concepts further and learn about vectors in two dimensions as well as components of vectors. As a very short recap, a vector has both a magnitude and a direction. There are…
GRADE 12 PHYSICAL SCIENCES.
VERSION 1 CAPS
This book deals with the physical sciences - physics and chemistry. All the sciences are based in the use of

In this lecture, the professor discussed fluctuations and noise, and the single photon.
Fundamentals of Matrix Algebra
A college (or advanced high school) level text dealing with the basic principles of matrix and linear algebra. It covers solving systems of linear equations, matrix arithmetic, the determinant, eigenvalues, and linear transformations. Numerous…
An Introduction to Matlab and Mathcad
This textbook, or really a “coursebook” for a college freshman-level class, has been updated for Spring 2014 and provides an introduction to programming and problem solving using both Matlab and Mathcad. We provide a balanced selection of…
APEX Pre Calculus
This text was written as a prequel to the APEXCalculus series, a three–volume series on Calculus. This text is not intended to fully prepare students with all of the mathematical knowledge they need to tackle Calculus, rather it is de-signed to…
Elementary Linear Algebra
This is an introduction to linear algebra. The main part of the book features row operations and everything is done in terms of the row reduced echelon form and specific algorithms. At the end, the more abstract notions of vector spaces and linear…
Mathematical Analysis. Volume I
This text is an outgrowth of lectures given at the University of Windsor, Canada. One of our main objectives is updating the undergraduate analysis as a rigorous postcalculus course. While such excellent books as Dieudonn´e’s Foundations of Modern…
Linear Algebra, Theory And Applications
This is a book on linear algebra and matrix theory. While it is self contained, it will work best for those who have already had some exposure to linear algebra. It is also assumed that the reader has had calculus. Some optional topics require more…
Linear Algebra with Applications. Open Edition
This textbook is an introduction to the ideas and techniques of linear algebra for first- or second-year
students with a working knowledge of high school algebra. The contents have enough flexibility to present
a traditional introduction to the…

An Introductory Course in Elementary Number Theory
Integers are the building blocks of the theory of numbers. This chapter contains somewhat very simple and obvious observations starting with properties of integers and yet the proofs behind those observations are not as simple. In this chapter
we…

Topics in Applied Mathematics
The concepts and basic topics in elementary Linear Algebra and Calculus are reviewed and generalized to Linear Analysis in this first unit. In particular, the dot product, the vector space of R 2(that is, the x − y plane in Plane Geometry), and…
Prealgebra
Prealgebra is designed to meet scope and sequence requirements for a one-semester prealgebra course. The book’s organization makes it easy to adapt to a variety of course syllabi. The text introduces the fundamental concepts of algebra while…
Linear Regression Using R: An Introduction to Data Modeling
Linear Regression Using R: An Introduction to Data Modeling presents one of the fundamental data modeling techniques in an informal tutorial style. Learn how to predict system outputs from measured data using a detailed step-by-step process to…
Environmental Biology
Environmental Biology is a free and open textbook that enables students to develop a nuanced
understanding of today’s most pressing environmental issues. This text helps students grasp the scientific
foundation of environmental topics so they can…

LIFE AND GENETICS
BI102A is a survey course that introduces the discipline of molecular biology and genetics, exploring topics including cell division, protein production, inheritance and gene regulation. This book focuses on putting those topics into an appropriate…
Mathematics for Elementary Teachers
This book will help you to understand elementary mathematics more deeply, gain facility with creating and using mathematical notation, develop a habit of looking for reasons and creating mathematical explanations, and become more comfortable…
Mechanics
This is a calculus-based book meant for the first semester of a first year survey course taken by engineering and physical science majors. It has a traditional order of topics whereby force is discussed before energy. It is divided into 17 chapters…
Adult Literacy Fundamentals Mathematics: Book 1
This is book one in a six-book series on fundamental mathematics for adult learners. These books include glossaries, self tests, practice requests, grades records, and unit tests. Ancillary Resources include the Instructor's Manual.
