Sure, but circles are geometric too :)

  Absolutely, but IMO circles have as little to do with sin and cos as triangles do :-)

    That seems ahistoric as per the meaning of the word. "Sine" is derived from the Sanskrit word for 'chord' as per its initial usage in determining the length of straight line segments between two arbitrary points on a circle.

    cos and sin are the x and y coordinates as you turn around the unit circle in unit speed.
