CASIO Rechner wissenschaftlich FX-991DE CW

FX - scientific calculator

Equations: Polynomial equations up to the 4th degree and additionally systems of equations with 4 unknowns can be solved with exact values and without approximation. The solution of an equation using the Newton method is also implemented. Matrices: Operations such as determinant, transposition, and identity matrix can be performed up to the dimension 4x4. Conversion to the reduced row echelon form (RREF) is also available. Vectors: Vectors up to the 3rd dimension can be calculated. The usual commands, such as dot product, cross product, angle, or unit vector are available. Integrals & Differentials: Differentials and integrals can be easily entered and numerically calculated using templates. Even in the value table, differentials and integrals are available. QR Code Function: Display content. The newly available QR code function allows results of the technical-scientific calculator to be visualized with a smartphone or tablet. Scanning the QR code: The result display is converted into a QR code by pressing a button on the calculator. This can then be captured with a smartphone or tablet. Visualization of content: With the help of ClassPad.net, graphs, diagrams, user aids, and tables of the captured data can be displayed and optimally presented. The new ClassWiz series differs from previous models as follows: 4-gray-scale display, new menu-driven operation, clear key layout, Math box (for dice and coin toss experiments), faster processor. Operation: The innovative operation and menu-supported navigation simplify the use of the calculator for students. Abbreviations and key combinations are largely avoided. Math box: The math box allows dice and coin toss experiments to be simulated. The relative frequencies of the sums can be listed.
