|sin, cos, tan||Maths||Trigonometry|
The basic trigonometric functions are displayed as a function of the angle and for a given angle:
sin x, cos x, tan x
The representation of each function on a unit circle is also shown.
- Switch between the three functions
- Change the value of the angle with the mouse and read the value of the function
Explain the relationship between both representations of the same function.
Increase the value of the angle and explain the result, especially for the tangent function.
Do the same for ever-decreasing values of the angle (you need not limit yourself to one turn!).
Explain the meaning of the red marks in both figures.
