(a) Eliminate the parameter to find a Cartesian equation of the curve. (b) Sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases. 16. x = t + 1 , y = t − 1

(a)

To determine

To find: obtain a Cartesian equation of the curve by eliminating parameter t .

Explanation

Given data:

The parametric equation for the variable x is as follows.

x=t+1 (1)

The parametric equation for the variable y is as follows.

y=t1 (2)

Calculation:

Solving parametric equation x to obtain value t .

x=t+1x2=t+1t=x21

Substitute t=x21 in the parametric equation y .

y=t1  =(x21)1y=x2</

(b)

To determine

To plot: The curve using the parametric equations. x=t+1 and y=t1 .
