Casio FX 85 ES Calculator

Product Information

Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates.

Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses. The calculation result for r and θ and for x and y are each assigned respectively to variables X and Y.FX-82ES Plus, FX-85ES Plus, FX-350ES Plus, FX-570ES Plus and FX-991ES Plus emulation software for school calculators The Natural Display (Natural-V.P.A.M.) shows mathematical expressions like roots and fractions as they appear in your textbook, and this increases comprehension because results are easier to understand. The keys have been made rectangular, making them easier to press. They are also easier to read because of larger text. Calculations can be input in the same form as they are written. When you press the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display.

To solve 2 x 2 + x - 3 = 0, for example, press in step 2, and then input the following for the coefficients (a = 2, b = 1, c = -3): 2 1 3 . Technical amendments and errors excepted. The sizes in figures do not correspond to the original sizes.When Linear Display is selected, pressing will cause the cursor to jump to the beginning of the calculation, while will jump to the end. These multiplication symbols (×) can be omitted. A multiplication symbol can be omitted when it occurs immediately before an opening parenthesis, immediately before sin or other function that includes parentheses, immediately before the Ran# (random number) function, or immediately before a variable (A, B, C, D, E, F, M, X, Y), scientific constants, π or e. You can use the following procedure in the EQN Mode to solve simultaneous linear equations with two or three unknowns, quadratic equations, and cubic equations. When Natural Display is selected, pressing while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing while the cursor is at the beginning will cause it to jump to the end.
