Law Of Sines
The law of sines is used to find angles of a general triangle. If two sides and the enclosed angle are known, it can be used in conjunction with the law of cosines to find the third side and the ...
Sinusoidal Waves
Sine waves can be represented mathematically and it can be shown that any wave can be constructed from an appropriate combination of sine waves (Fourier Series).
Fourier Analysis
The mathematician Fourier proved that any continuous function could be produced as an infinite sum of sine and cosine waves. His result has far-reaching implications for the reproduction and ...
Law Of Cosines
The law of cosines for calculating one side of a triangle when the angle opposite and the other two sides are known. Can be used in conjunction with the law of sines to find all sides and angles.
Physics revision
A revision of school physics including energy, sine waves, Hooke's Law, EM spectrum and electricity.
Teacher developed Earth and Space Science Lessons and Classroom activities
