Coordinate Conversions

Conversions can be performed between rectangular and polar coordinates.

P (x, y )

P (r,

)

Rectangular coordinate Polar coordinate

• Before performing a calculation, select the angular unit.

• The calculation result is automatically stored in memories.

•Value of r: R memory

•Value of θ: θ memory

•Value of x: X memory

•Value of y: Y memory

• r and x values are stored in the last answer memory.
