sin, cos, tan Maths Trigonometry
Sin-M1-13.jpg

Overview:

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.

You may:

  • Switch between the three functions
  • Change the value of the angle with the mouse and read the value of the function


Suggestions:

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.
