Tangent Graphing Question

  1. Oct 10, 2006 #1
    Why does the period of a tangent function = 180 degrees, and the sine and cosine functions have periods of 360 degrees. Also i dont understand why asymptotes are included in the tangent graph, and not the other two

    If someone could clarfy this for me id be very thankful

    It is because the tan(x) function is a ratio of sin(x) and cos(x).

    As x gets near [itex]\pi/2}[/itex], cos(x) gets very near from 0, while sin(x) gets near 1. So tan(x) near [itex]\pi/2}[/itex] gets very big, hence the assymptote at [itex]\pi/2}[/itex]. The same phonomenon explain the other assymptotes.
