Aim of the applet
Graphical representation of the functions sine, cosine and tangent.
Input data
The point P that can slide on the circumference to vary the angle θ. (Red)
The angle between the vector pointing to P and the axis 0X positive. (Green)
Output data
The graph of the function sin(θ). (Blue)
The graph of the function tan(θ). (Green)
The graph of the function sin(θ). (Red)
First steps
- Place the mouse over the red point in the circumference and slide on it.
Stop at the first angle in which match sine and cosine.
Where do the same thing occurs again?
- It is important to know the values of angles of sine and cosine that mark the quadrants.
In which case the tangent is infinite?
- Set the intervals at which the sine and cosine are negative, respectively.
