Changes log for the MEI AS Pure Maths Tests
 7 August 2007
 Some minor updates to Geometry: Equation of a Circle
and the way some suvat equations are displayed and the position of the buttons on
Differential Equations: Second Order
 10 April 2007
 Bug fixed in Polynomials With New Roots; buttons now change to show when the mouse is over them and
when clicked. This, as withthe change in button style, is so that button increase in size with the rest of the text
when the font is changed in the browser ( Zoom or Text Increase/Decrease depending on your browser)
as do all equations in oder to help visually impaired users.
 4 April 2007
 The second order differential equations test now has questions on particular solutions too.
To select these explicitly, include "?qu=partic" or "?qu=gen" after the URL.
 3 April 2007
 Minor changes to Geometry: Equation of a Circle and
Polynomial Differentiation: Gradient and Normal;
new test Complex Numbers: Multiplying and Dividing in Polar Form
 15 March 2007

involving logs and exponentials
 12 December 2006
 New Test: Statistics: Linear Coding
 5 December 2006

 16 November 2004
 New Test: Complex Numbers:Polar Form
 3 November 2006
 The Mechanics: suvat Tests answers now include a pulldown box to explicityl state how many solutions
there are. If there are two solutions, including negative values, both must be given.
The Choosing a suvat equation (multiple choice) Test can now
have a URL parameter "fixedorder" to maintain the same order of choices in all questions as in
MechSuvatEquns.html?fixedorder. Remember that to preserve this option,
you must use the Browser "Reload" ("Refresh") button as New Question (and the test title) generate questions of
the default type.
 29 October 2006
 New Test: Mechanics: Applying suvat equations which can
also be parameterised as mentioned under 27 October 2006.
 27 October 2006
 Mechanics: suvat equations, two tests added:
Choosing a suvat equation (multiple choice) and
Solving suvat equations (algebraic manipulation)
which can have the variable to find specified and/or the missing variable e.g.:
 1920 October 2006
 Differential Equations added: First Order (separation of variables),
Second Order (Auxiliary Equation, distinct real roots)
 618 October 2006
 Arithmetic Series: Terms,
Geometric Series: Terms, and to display of negative fractions on all
pages.
 1 September 2006
 All Tests involving complex numbers can now have the symbol used for the
imaginary value changed to
by putting "?imag=i" (change i to I, j or J too) at the end of the URL
or, if there are other parameters (eg ref=12345) then put ",imag=i" at the end
The Calculator has a new look.
New test
Powers and Logarithms: Modelling Population Growth,
Extensive changes to
Simple Trig Values
 15 August 2006
 Polynomials with New Roots by default chooses a
quadratic, cubic or quartic. It now has options to limit the maximum degree to
only quadratic ;
only quadratic or cubic.
 4 November 2004
 New test on Graph Transformations (translations and shears) added.
 2 November 2004
 New Question button romoved  click on the Title of a test now to generate a new question;
Partial fractions test added to Polynomials.
 18 August 2004
 minor updates to Polynomial Definite Integration;
new: Algebra: Complete the Square,
Polynomials: Remainder Theorem
 13 August 2004
 Revised tests: Arithmetic Series: Formula manipulation
 Geometric Series: Formula Manipulation
 Slope of a line  Coordinates and Angles
 Equations from Logx and LogLog graphs
 Differentiation: Gradient and Normal
 5 August 2004
 Several tests have been corrected. Tests affected have revision date 4 or 5 August 2004.
 21 July 2004

 Tests with a specific question type are now implemented. Use the links above where variations in questions
are available. Note that 'e.g.' introduces specific tests (fixed question) to illustrate special features
and are not selectable by the test page (the type of question is generated at random). Use the initial link for all types of questions
to be generated at random.

The HELP page now reflects the action of the buttons.
 20 July 2004
 Some terms now have a reminder
if the pointer (mouse) rests on the word without clicking e.g. Geometry: Collinear Points
All the buttons have the feature too.
 4 June 2004
 Vector Magnitude, Operations and Angle now include 3dimensional vectors (the lines are 2D and the plane is 3D).
 2 June 2004
 New: Quadratic and Line Intersection, Polynomial Division; Series AP Formula manipulation; Series GP formula manipulation;
Revised: Arithmetic Series Terms;
 22 May 2004
 Most tests altered; globals files and some images updated.
 19 May 2004
 New: Powers: Fractional and negative; Vectors: Magnitudes;
Operations; Angle between two vectors; Vector Equation of a Line; Vector Line to
Cartesian form, Vector Plane Equation using the Normal.
 20Apr04
 Updated GeomCircleTanNorm, GeomCircleAndLine,
solution of quadratics with a constant factor.
 28Apr04
 Several tests updated, corrected and worked solution changed.
The Help and New Question buttons now appear at
the top of the page on either side.
 24Apr04
 Diagrams added to the Worked Solutions for Area Of A Triangle Given 3 Sides and
Area Of A Triangle Given 2 Sides and An Angle.
 16Apr04
 New: Geometry: Circle and Line Intersection.
New: Algebra: Simplifying Surds.
New: Logarithms: Equations from LogLog and Logx graphs.
The generator of numbers for new Tests has been improved. The examples above and any Test's URL
containing a reference number will now have a NEW reference number.
 2Apr04
 New tests are Geometry: Equation of a Circle, Geometry: Tangent and Normal to a Circle,
 22mar04
 Polynomial Curve Sketching:Shape added.
 20Mar04
 Links can now be added at the end of any Test by putting them in the file "links.js" which
contains instructions and an example.
 19Mar04
 The calculator now has trig and inverse trig functions, in degrees or radians,
and computes logs to any positive base.
 17Mar04
 The Calculator is now more compact and has a new icon.
Several more Tests now contain the Calculator icon.
Point names on triangles etc are now consistently boldened.
Algebra: Form and Solve Quadratic Equations now detects if the Formula is needed or
if the quadratic can be factored and gives the appropriate method in the Worked Solution.
 12Mar04
 New Test: Polynomials with New Roots  the most complicated test in this suite.
 11mar04
 New Tests: Sum and Product of Roots of a Polynomial, Polynomial from Roots
 10Mar04
 New Tests: Polynomial Definite Integration and Indefinite Integration.
The Calculator is now a separate window and is therefore available for all the tests although only
certain ones will give an explicit link to it, as indicated above.
