Question in All questions
A function $f(x) = cln(ax^2+bx) x$ is sketched and tangent is also drawn. The equation of the tangent line is asked for and $x$coordinate for horizontal tangent is asked for. Calculator.

Question in Analytical Methods: LO1  Algebraic
Split $\displaystyle \frac{ax+b}{(cx + d)(px+q)}$ into partial fractions.

Question in CHY1201  SpectroscopyThe reduced masses are precalculated 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 Adelle's workspace
An applied example of the use of two points on a graph to develop a straight line function, then use the t estimate and predict. MCQ's are also used to develop student understanding of the uses of gradient and intercepts as well as the limitations of prediction.

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.

Question in Howtos
A line with random $x$ and $y$ intercepts is plotted, and you have to drag two dots over the points where the line crosses the $x$ and $y$ axes.

A randomised line in a GeoGebra worksheet  construct the definition of the line manually Should not be usedQuestion in Howtos
Construct a line in a GeoGebra worksheet by writing its definition string by hand.
This isn't a very neat way of doing this. It's easier to define two points in GeoGebra, then make a line through those points. You can set the positions of the points from Numbas using vectors.

Question in Howtos
Construct a line through two points in a GeoGebra worksheet. Change the line by setting the positions of the two points when the worksheet is embedded into the question.

Question in PV EnglishFormulate a recurrence relation (= difference equation) and solve this recurrence relation.

Question in Transition to university
Use two points on a line graph to calculate the gradient and $y$intercept and hence the equation of the straight line running through both points.
The answer box for the third part plots the function which allows the student to check their answer against the graph before submitting.
This particular example has a positive gradient.

Question in Blathnaid's workspace
Finding the modulus and argument (in radians) of four complex numbers; the arguments between $\pi$ and $\pi$ and careful with quadrants!

Question in Linear Programming
