Preface Preface

Typing answers in interactive questions.

This book contains interactive STACK questions. When you enter your answers in response to a question, you will have to adhere to certain syntax. In the following, we show the most common examples.
🔗
In STACK you often need to enter an answer which is an algebraic expression. You should type in your answers using the same syntax as that used in the symbolic mathematics package Maxima.
🔗
The syntax is broadly similar to the syntax used for mathematical formulae in graphical calculators, general programming languages such as Maple, Java, C and Basic and in spreadsheet programs, so you will find it useful to master it.

  • Use a star for multiplication. For example, \(3x\) should be entered as 3*x.
    🔗
  • Use a caret (^) for raising something to a power: for example, \(x^2\) should be entered as x^2
    🔗
  • \(x^{-2}\) should be entered as x^(-2)
    🔗
  • \(\displaystyle x^{\frac{1}{3}}\) should be entered as x^(1/3)
    🔗
  • Brackets are important to group terms in an expression.
