"Then you have come to the right place," Elias said, reaching behind him for a small, well-thumbed manual. "But let’s skip the reading and do the storytelling. Let me tell you the biography of your calculator." casio fx50fh ii manual
Assigns a value or calculation output to a variable memory (A, B, C, D, X, Y, M).
Use Pol( and Rec( (found above the + and - keys) to switch between rectangular and polar coordinates.

Single-variable statistical calculations (e.g., standard deviation).
The fx-50FH II is a with 680 programming steps, 24 scientific constants, and 40 built-in formulas (e.g., quadratic equations, circle properties, standard deviation).
By default, the calculator handles trigonometry in degrees. To change this: → A : π × A² Occurs when
