Question in HowtosA custom marking algorithm picks out the names of the constants of integration that the student has used for the $\cos$ and $\sin$ terms in their answer, and replaces them with $A$ and $B$ respectively, before comparing with the correct answer. This way, the student is free to choose the names for their constants of integration.

Question in PV English

Question in Engineering Statics
Solve a random oblique triangle for sides and angles.

Question in Andrew's workspace
Two questions testing the application of the Cosine Rule when given two sides and an angle. In these questions, the triangle is always acute and both of the given side lengths are adjacent to the given angle.

Question in Andrew's workspace
A question testing the application of the Cosine Rule when given three side lengths. In this question, the triangle is always acute. A secondary application is finding the area of a triangle.

Question in Adelle's workspace
Given a description in words of the costs of some items in terms of an unknown cost, write down an expression for the total cost of a selection of items. Then simplify the expression, and finally evaluate it at a given point.
The word problem is about the costs of sweets in a sweet shop.

Question in Demos
Contains some extremely basic code to do symbolic differentiation: it can give the derivative of terms of the form $x^n$, $sin(x)$ and $cos(x)$, and apply the chain rule.

Question in Anna's workspace
Calculate the local extrema of a function ${f(x) = e^{x/C1}(C2sin(x)C3cos(x))}$
The graph of f(x) has to be identified.
The first derivative of f(x) has to be calculated.
The min max points have to be identified using the graph and/or calculated using the first derivative method. Requires solving trigonometric equation

Question in Wiskunde voor bedrijfswetenschappen ACalculate the competitive price as the minimum of the average cost, given a production function in one variable for a situation of perfect competition.

Question in Content created by Newcastle University
Find angle between plane $\Pi_1$, given by three points, and the plane $\Pi_2$ given in Cartesian form.
The calculation of $cos(\alpha)$ at the end of Advice has fractionNumbers switched on and so the result is presented as a fraction, which can be misleading. Best if calculation is followed through without using fractionNumbers.

Question in Content created by Newcastle University
Given a generating matrix for a binary linear code, construct a parity check matrix, list all the codewords, list all the words in a given coset, give coset leaders, calculate syndromes for each coset, correct a codeword with one error.

Question in Content created by Newcastle University
Find the cosine of the angle between two pairs of 3D and 4D vectors.
The calculations and answers are correct, however the Advice should display the interim calculations of the lengths of vectors and their products to say 6dps. At present the student may be mislead into using 2dps at each stage  the instruction at the start of Advice is somewhat confusing.
