This branch of math, known as trigonometry, has everyday practical applications such as construction, GPS, plumbing, video games, engineering, carpenter work and air flight navigation. To memorize a ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around ... also change. The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) can be plotted.

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 ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around ... depending on the value of \(\theta\). The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) ...
