This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...

Graphs of Sine and Cosine 1.2 An applet illustrating ... Construction of the Tangent to a Parabola 2.1 An applet illustrating how the tangent to a parabola is obtained through successive secant lines.

The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the sine function by the cosine function. Microsoft Excel simplifies the ...

Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations ...
