About the book

This book gives you fully worked solutions for every question (discussions, investigations and projects excepted) in each chapter of the Haese & Harris Publications Mathematical Studies SL textbook.

Correct answers are given for the questions in each chapter in the book:

• Number sets and properties
• Measurement
• Sets and Venn diagrams
• The rule of Pythagoras
• Descriptive statistics
• Linear and exponential algebra
• Coordinate geometry
• Quadratic algebra
• Function notation and quadratic functions
• Numerical trigonometry
• Perimeter, area and volume
• Sequences and series
• Financial mathematics
• Probability
• Logic
• Exponential and trigonometric functions
• More functions
• Two variable statistics
• Introductory differential calculus

Correct answers can sometimes be obtained by different methods. In this book, where applicable, each worked solution is modelled on the worked example in the textbook.

Be aware of the limitations of calculators and computer modeling packages. Understand that when your calculator gives an answer that is different from the answer you find in this book, you have not necessarily made a mistake, but the book may not be wrong either.
