Chapter 10: Q. 25. (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.
$x = \sin^{2} t, y = \cos^{2} t; 0 \leq t \leq 2 π .$

Short Answer

Expert verified

The equation is $x + y = 1$ .

Step by step solution

Step 1. Given information.

$x = \sin^{2} t, y = \cos^{2} t$ is given.

Step 2. Form the graph and equation.

we form the rectangular equation by eliminating t in the equation-

$x = \sin^{2} t y = \cos^{2} t \sin^{2} t + \cos^{2} t = 1 x + y = 1$

Graph the curve defined by the parametric equations -

$t$	$x$	$y$	$(x, y)$
$0$	$0$	$1$	$(0, 1)$
$\frac{π}{2}$	$1$	$0$	$(1, 0)$
$π$	$0$	$1$	$(0, 1)$
$2 π$	$0$	$1$	$(0, 1)$
