Trigonometry
This sub-collection of resources from the Virtual Text Book collection contains five resources designed for use on an interactive whiteboard to aid the teaching and learning of a variety of topics in ‘Trigonometry'. Each resource is an interactive Excel worksheet to encourage teacher-student interaction. The topics covered are:
• aSin(x) + bCos(x)
• Modelling: Depth of Water in a Tidal River
• Radians: Arcs and Sectors
• X = Cos, Y = Sin
• Volumes of Revolution

aSin(x) + bcos(x)
This group of interactive excel worksheets look at the series of identities of the form
aSin(x) ± bCos(x) and aCos(x) ± bSin(x),
where a=RCos(α), b = RSin(α), R=√(a...
Modelling: Depth of Water in a Tidal River
This excel file looks at using the sine curve to model the water depth in a tidal river.
The first interactive sheet shows how the Earth’s orbit around the Sun can be modelled by the sine curve. One or two cycles can...
Radians: Arcs and Sectors
This collection of interactive excel sheets look at radians, arc length, sector area, converting to and from degrees, and other related problems.
The first sheet displays a sector of a circle and corresponding...
Trigonometry: X=cosθ,Y=sinθ
This collection of interactive excel sheets looks at a circle of radius 1 and the corresponding values generated for cosθ and sinθ.
The first interactive sheet illustrates that for the unit circle, X = cosθ and Y =...
