This applet shows how the graphs of sin (θ) and cos (θ) follow directly from the definition of these functions. Move the slider to change the angle. Observe that after the point moves once around the ...

National 5 Working with the graphs of trigonometric functions Phase angle Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

Trigonometric functions can have several solutions. Sine, cosine and tangent all have different positive or negative values depending on what quadrant they are in.
