 Coordinate conversion (Pol (x,y), Rec(r, ))
• Calculation results are automatically assigned to variables E and F.
• Example 1: To convert polar coordinates (r=2, =60°)torectangularcoordinates(x,y)(Deg)
• Press todisplaythevalueofx,or to display the value of y.
• Example 2: To convert rectangular coordinates (1, 3) to polar coordinates (r, ) (Rad)
• Press to display the value of r, or to display the value of .
 Engineering notation calculations
• Example 1: To convert 56,088 meters to kilometers
• Example 2: To convert 0.08125 grams to milligrams
