• Exam (5 questions) in QQI
This is a sample of a timed Numbas Exam.
• Question

Utilizza un grafico di una retta $y=mx+c$ incluso da Geogebra con coefficienti casuali impostati da NUMBAS. Il grafico contiene anche un punto $P$ di coordinate casuali impostate da NUMBAS. L'esercizio chiede di determinare l'equazione della retta e quelle delle rette parallela e perpendicolare per $P$.

• Question

A sneak peek at a really clever integration of GeoGebra with Numbas.

• Question

Numbas representation of the Metacentric Height fluid mechanics laboratory for first year Engineering students.

Students should answer this question after completing the laboratory and the associated Excel template, including the relevant plots.

The first question tests their capacity to correctly calculate metacentric heights, the remaining questions evaluate their graph interpretation skills.

• Question
Attempt 1 at creating a Numbas-based representation of the Hydrostatic Thrust laboratory for 1st stage Engineering students at Newcastle University.
• Question in Demos

The student is asked to enter an approximation to $\sqrt{n}$, where $n$ is not a square number, to 20 decimal places.

This question is a demonstration of the high precision arithmetic in Numbas v4.

• Question

Practice with adding, subtracting and dividing basic algebraic fractions

• Question in How-tos

Update: you can now use the conditional visibility button to do this more easily - see the documentation.

If the statement or advice for your question differs greatly depending on a random variable (for instance, if you're picking from a selection of scenarios), you only want to show content for the relevant scenario.

This question shows one way of doing that.

• Question in How-tos

This question is out of date: use the currency function instead.

• Question in How-tos

Display a number like "1234" as "1,234".

This question is out of date: the formatnumber function can format numbers using several different notational styles.

• Question in Demos

Given the gradient of a slope and the coefficient of friction for a mass resting on it, use the equations of motion to calculate how it moves.

Includes a GeoGebra rendering of the model.

• Question in Demos

Customised for the Numbas demo exam

Motion under gravity. Object is projected vertically with initial velocity $V\;m/s$. Find time to maximum height and the maximum height. Now includes an interactive plot.

Some examples of Numbas questions used in computing modules in the School of Mathematics, Statistics & Physics at Newcastle University
• Question
The reduced masses are pre-calculated for this question and included in a list. It would be more elegant to program Numbas to permute atoms together to generate diatomic molecules while constraining the permutations to those which are chemically/physically reasonable, so as to allow calculation of each reduced mass directly from the atomic masses- but organising this with high computational efficiency might be a significant programing task (add to "to do" list).

Question in Demos

Customised for the Numbas demo exam

Factorise $x^2+cx+d$ into 2 distinct linear factors and then find $\displaystyle \int \frac{ax+b}{x^2+cx+d}\;dx,\;a \neq 0$ using partial fractions or otherwise.

Demo question showing how to use the matrix maths functions in JavaScript.

• Question in How-tos

A couple of different ways of showing the correct answer to a single part as soon as the student submits an answer. One way allows the student to change their answer, while the other locks the part.

A third part includes a "reveal answers to this part" button, which allows the student to choose to reveal the answer to the part.

Think very carefully before using this: by revealing the answer, you are removing the opportunity for the student to later on realise they've got that step wrong, as a consequence of some further work. It's often possible to use adaptive marking to use the student's answer in place of the correct answer in later parts.

• Question in How-tos

A table showing how to substitute raw LaTeX code into question text.

NOTE: You probably don't want to do this! There's usually a more robust way, where you get Numbas to make the expression for you.
