Calculating gradient and finding intercept from a geogebra graph.
-
Students are supposed to use Excel (or similar) to find the answers (e.g., enter coordinates of two points then plot and add trendline).
Uses an embedded Geogebra graph of a line y=mx+c with random coefficients set by NUMBAS.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Vigenère Cipher using a four-letter key. Message letters are generated uniformly at random from the English alphabet, as are the key letters. Students are expected to be able to map English letters onto elements of Z26 in the usual order.
-
Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-bit message with the Vernam Cipher. The message and the key are uniform and independently generated eight-bit strings.
-
Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Substitution Cipher. Message letters are generated uniformly at random from the English alphabet and the key is a uniformly chosen random permutation of the alphabet. Students are expected to be able to map English letters onto elements of Z26 in the usual order.

Question in Ugur's workspace
Calculate a repeated integral of the form I=∫10∫xm−10mf(xm+a)dydx
The y integral is trivial, and the x integral is of the form g′(x)f′(g(x)), so it straightforwardly integrates to f(g(x)).

Question in Ida's workspace
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 Standard Maths
Students are given the bearings and distances of 2 consecutive straight line walks. They are asked to find the distance from the starting point to the endpoint. They are given a diagram to assist them.
The bearings and distances are randomised (any bearing, distances between 1.1 and 5.). Bearings can be given as either compass bearings or true bearings.
