Answer
$\left( -0.670,5.157 \right)$
Work Step by Step
To determine the rectangular coordinate from the polar coordinate, follow these steps:
Step I: Press 2nd and then press the APPS key to open the Angle Menu.
Step II: Press 7.
Step III: Enter the point $\left( r,\theta \right)$ and press enter to display x in the $\left( x,y \right)$ rectangular form of the point.
Thus, $x=-0.670$
Step IV: Follow Step I and Step II and then press 8.
Step V: Enter the point $\left( r,\theta \right)$ and press enter to display y in the $\left( x,y \right)$ rectangular form of the point.
Thus, $y=5.157$
Hence, the rectangular coordinate of $\left( 5.2,1.7 \right)$ is $\left( -0.670,5.157 \right)$.
