Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...
Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the ... This applet shows how the graphs of sin(θ) and cos(θ) follow ...
This circle has the centre at the origin and a radius of 1 unit. The point P can ... on the value of \(\theta\). 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 the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...
