Download a file and scan the values into R to obtain a numeric vector of values. Then use R to explore your numeric vector in order to find the answers to these questions.

Introduction to first order recurrence relations with a simple example, including homogenous and non-homogenous solutions.

Given mass and volume of an object in SI units, calculate its density. The units are given at different orders of magnitude.

A mathematical expression part whose answer is the product of two matrices, $X \times Y$.

By setting the "variable value generator" option for $X$ and $Y$ to produce random matrices, we can ensure that the order of the factors in the student's answer matters: $X \times Y \neq Y \times X$.

Find the stationary points of the function: $f(x,y)=a x ^ 3 + b x ^ 2 y + c y ^ 2 x + dy$ by choosing from a list of points.

Inputting the values given into the partial derivatives to see if 0 is obtained is tedious! Could ask for the factorisation of equation 1 as the solution uses this. However there is a problem in asking for the input of the stationary points - order of input and also giving that there is two stationary points.

Four questions on finding least upper bounds and greatest lower bounds of various sets.

Given sum of sample from a Normal distribution with unknown mean $\mu$ and known variance $\sigma^2$. Find MLE of $\mu$ and one of four functions of $\mu$.

Simple probability question. Counting number of occurences of an event in a sample space with given size and finding the probability of the event.

Eight questions on finding least upper bounds and greatest lower bounds of various sets.

Trying out something: get the student to enter a set for each of "regular singular points" and "essential singular points".

Find and classify singular points of a second-order ordinary differential equation.  One equation is chosen from a selection of 10.

Two ordered data sets, each with 10 numbers. Find the sample standard deviation for each and for their sum.

Provided with information on a sample with sample mean and standard deviation, but no information on the population variance, use the t test to either accept or reject a given null hypothesis.

Power series solution of $y''+axy'+by=0$ about $x=0$.

Two ordered data sets, each with 10 numbers. Find the sample standard deviation for each and for their sum.
