Trigonometry Problems - By Sean Kiernan
The Purpose Of This Webpage Is To Illustrate The Principles Involved In Solving Trigonometry Problems - Specifically Right Angled Triangles Using The Sine Rule You Create A Triangle On Screen And The Applet Solves For The Adjacent Side Explaining The Steps Involved In The Text Box Below [View Applet]

Solving Trigonometry Problems Using The Sine Rule - By Enda King
This Applet Uses The Sine Rule To Solve A Simple Trigonometric Problem. The User Enters The Length Of One Side And Two Angles Of A Triangle, And The Applet Will Draw The Entire Triangle, Line By Line, Giving All The Calculations Used In The Construction Of The Lines. [View Applet]

Solving Simple Trigonometry Problems. - By Ryan Sherlock
This Applet Shows Some Basic Priniciples To Solving Simple Trigonometry With The Sine And Cosine Formulae. It Shows How Changes In The Lengths And Angles Of A Triangle Effect The Different Formulas. [View Applet]

Graphs Of Trigonometric Functions - By Beate West
Here You Can Draw Functions Of The Form F(x) = A * Sin(b * X), F(x) = A * Cos(b * X), F(x) = A * Tan(b * X). You Just Have To Enter A And B And Choose A Function. But, Be Careful When Entering The Factor A, The Function Will Only Be Drawn Correctly If A Is Between -5 And 5. [View Applet]

Sine Rule - By Peter Kelly
The Sine Rule Is An Essential Part Of Trigonometry On The Mathematics Leaving Certificate Course. The Sine Rule Can Be Seen On Page 9 Of The Log Tables. The Following Applet Explains How To Derive The Sine Rule Given Any Triangle. [View Applet]

The Cosine Rule - By Mary Howlett
In This Applet When I Click A Button It Displays Two Triangles And Then When I Click The Button Again It Displays The Combined Triangle And All The Relevant Formula For The Applet. This Applet Aims To Illustrate The Cosine Rule Using These Three Triangles [View Applet]

The Unit Circle - By Martin Hehir
This applet gives a brief demonstration of the principles behind which the unit circle operates. It then allows the user to enter an angle and demonstrates how the function (SIN, COS or TAN) is performed upon it. [View Applet]

Explanation of Radians - By Martin Hehir
This applet demonstrates the principles on which radians operate as a measure of an angle. It takes the form of a slideshow. A single button 'Continue Demonstration' advances from slide to slide. It is important to state that the same person that made the demonstration of the unit circle made this applet. Therefore, much of the code was reused. [View Applet]
