Question in OCR L3: Unit 1  Mathematics for engineering
Solving pair of simultaneous (linear) equations

Question in Linear Algebra 1st year
To understand matrix multiplication in terms of linear combinations of column vectors.

Question in Linear Algebra 1st year
Abstract linear combinations. "Surreptitious" preview of bases and spanning sets, but not explicitely mentioned. There is no randomisation because it is just an abstract question. For counterexamples, any valid counterexample is accepted.

Question in Linear Algebra 1st year
This allows the student to input a linear system in augmented matrix form (max rows 5, but any number of variables). Then the student can decide to swap some rows, or multiply some rows, or add multiples of one row to other rows. The student only has to input what operation should be performed, and this is automatically applied to the system. This question has no marks and no feedback as it's just meant as a "calculator".

Exam (32 questions) in Standard Maths
This is a set of questions for students to practice identifying parabolas, hyperbolas and exponentials.
There are also a few questions asking students to draw graphs, and to evaluate the curves at specific points.
10 questions are selected from a larger pool.
In the first question students are asked to identify the type of a graph.
In the second question students are asked to identify the type of an equation.
Then next 6 questions are basic questions about evaluating points on a curve or matching curves and equations.
The last 2 questions are applications  e.g. compound interest, displayed as an equation, a table or a graph.

Exam (5 questions) in Standard Maths
Practise solving simultaneous linear equations graphically and algebraically.

Question in 1202
A graph is drawn. A student is to identify the derivative of this graph from four other graphs.

Question in 1202
A graph is drawn. A student is to identify the derivative of this graph from four other graphs. There are four version of this question: I: cubic, II: linear, III: quadratic, IV: sinusoisal.

Question in Standard Maths
Students are shown a graph of the value of a machine over time. The line equation is randomised.
They are asked to evaluate value at a given time, and the time at which a given value is reached. They are asked when the machine has no value, and the range of times over which the model is valid. They are also asked to explain the physical meaning of the gradient.

Question in Standard Maths
Students are given a word problem with the distance travelled and the time taken by a cyclist. They need to choose the correct form for the linear equation, compute the gradient, and plot the line.
The distance travelled and time taken are randomised.
Speed, distance and time are all integer values.
