Chapter 10: Q. 9. (page 694)

In problem graph the curve whose parametric equations are given and show its orientation. Find the rectangular equation of each curve. Verify your graph using a graphing utility.
$x = t + 2, y = \sqrt{t}; t \geq 0$

Short Answer

Expert verified

The answer is $y = \sqrt{x - 2} .$

Step by step solution

Step 1. Given information.

$x = t + 2, y = \sqrt{t}; and t \geq 0$ is given.

Step 2. Calculation.

Graph the curve defined by the parametric equations -

$x = t + 2, y = \sqrt{t}; t \geq 0$

$t$	$x$	$y$	$(x, y)$
$0$	$2$	$0$	$(2, 0)$
$1$	$3$	$1$	$(3, 1)$
$2$	$4$	$\sqrt{2}$	$(4, \sqrt{2})$
$3$	$5$	$\sqrt{3}$	$(5, \sqrt{3})$

We find the rectangular equation by eliminating the parameter t from the parametric equations.

$y = \sqrt{t} y^{2} = t$

Put the value of t in the equation -

role="math" localid="1648227471219" $x = t + 2 x = y^{2} + 2 y^{2} = x - 2 y = \sqrt{x - 2}$

Thus, the equation is $y = \sqrt{x - 2} .$
