# Answer calcPad Questions

WebAssign calcPad questions are displayed with a rectangular answer box similar to answer boxes used for other question types, but when you click a calcPad-enabled answer box, the calcPad palette opens, allowing you to answer the question with a correctly formatted mathematical expression.

Note:

- Adobe
^{®}Flash^{®}Player, version 10 or later is required. See Required Browser Plug-Ins. - Do not use function notation — for example, f(x) — when answering questions. WebAssign cannot grade answers that use function notation.

- Flash is not required.
- The location and appearance of the tools palette is different on iPad.

- tool palette
- When you click the answer box, a tool palette is displayed beside the question. You can click buttons in the palette to insert notation in your answer.
- placeholder boxes
- Some buttons insert placeholder boxes to show you where you can type numbers, variables, or expressions. For example, if you insert a fraction, placeholder boxes are displayed for both the numerator and denominator.
- button groups
- Many buttons are grouped together in expandable button groups. For example, the Trig button group includes buttons for trigonometric functions like sine and cosine.

## To answer a calcPad question:

- Answers are case-sensitive;
`x`and`X`are not the same. - Do not type commas in numbers; 5,280 is not correct.
- In a comma-delimited list that includes fractions, put the commas between fractions and not in the numerator or denominator.
- Do not enter mixed numbers, for example, 2½. Instead, use decimals or improper fractions.
- When entering scientific notation, always use a lowercase e, for example, 1.23e-5.
- Express angles for trigonometric functions in radians.
- Keyboard characters that are not mathematically useful — for example,
`&`,`,``@`, and foreign language characters — are intentionally not displayed when typed. To enter Greek characters, use the buttons or keyboard shortcuts for the tool. - Use parentheses to specify the arguments of functions explicitly, for example,
sin(3
`x`).Note: If you omit parentheses, spaces are used to determine the argument of the function and your answer might not be graded as you expect. For example:`sin3`is graded as sin(3) ×`x``x``sin 3`is graded as sin(3`x``x`)
