Question in Christian's workspace
Write down the Newton-Raphson formula for finding a numerical solution to the equation emx+bx−a=0. If x0=1 find x1.
Included in the Advice of this question are:
6 iterations of the method.
Graph of the NR process using jsxgraph. Also user interaction allowing change of starting value and its effect on the process.

Question in Content created by Newcastle University
A graphical approach to aiding students in writing down a formal proof of discontinuity of a function at a given point.
Uses JSXgraph to sketch the graphs and involves some interaction/experimentation by students in finding appropriate intervals.

Question in Christian's workspace
Find a regression equation.
Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.

Question in Graeme's workspace
This question plots a general amplitude modulated carrier signal defined by vs(t)=(VDC+Vmcos(2πfmt))cos(2πfct), where VDC is a DC offset, Vm is the message amplitude, fm is the message frequency and fc is the carrier frequency (fc=20fm in this question). The student must identify the values of VDC and Vm and enter these values into the appropriate gaps in the equation of the AM signal.
