    Find when these parametic curves cross the x and y axis:

    1) x = 1 - cos(t) , y= sin(t)

    2) x= sin(t) y=cos(t)^2

    obviously you sub when x=0 and when y=0 in.

    Just rearrange and solve for t when x or y=0.

    1) y-axis: x=0 so cos(t)=1 so t=0. y=sin(0)=0, so (0,0).
    x-axis: y=0 so sin(t)=0 so t=0 or pi. Gives (0,0) and (2,0).
