Polar coordinate system
• The variable θ is always displayed in the left end
column.
• For table values (R), R1 to R3 are displayed on the
first screen.
• To show values R4 to R6, press > to horizontally scroll the screen.
• For values θ, R1 to R6, up to 7 digits, including a sign and decimal point can be
displayed.
• A 10-digit value of the column where the cursor pointer is currently located is
displayed on the bottom line of the screen.
• The cursor pointer can be moved using <> ≤≥.

n
), up to 7 digits,
including a sign and decimal point can be displayed.
