Coordinate Conversion (Pol (x, y), Rec (r, θ))
• Calculation results are automatically assigned to variables E and F.
•
Example 1: To convert polar coordinates (r=2, θ=60°) to rectangular coordinates (x
r
y] (Deg)
• Press RCL E to display the value of x, or RCL F to display the value of y.
• Example 2: To convert rectangular coordinates (
) to polar coordinates ( )
(Rad)
• Press RCL E to display the value of r, or RCL F to display the value of θ.
