(551, #9) Sketch the curve represented by the parametric equation
Then eliminate the parameter to find the Cartesian equation of the curve.
Solution : This is the parametric plot for
.
As for the Cartesian equation:
Using the identity ,
we get the equation x+y=1.
Thus the parametric plot of
lies on the line y = 1-x.
Then eliminate the parameter to find the Cartesian equation of the curve.
.
,
we get the equation x+y=1.
lies on the line y = 1-x.
