Koristi grijeh, cos, tan za sinus, kosinus i tangens. Inverzne funkcije (grijeh-1, cos-1, tan-1) se pristupa putem 2. F.
Logaritamske i eksponencijalne funkcije
Keys include log (common logarithm), ln (natural logarithm), 10x, i ex.
Power and Root Functions
Iskoristi x2, x3, √ (square root), and 3√ (cube root).
Memorijske funkcije
The calculator has 8 temporary memory buttons. Use STO (Store) to save a value and RCL (Recall) to retrieve it.
Statistički proračuni
Da biste ušli u statistički način rada, pritisnite MODE zatim odaberite STAT. The calculator supports 1 and 2 variable statistics. Refer to the on-screen prompts for data entry and calculation of statistical values like mean, standard deviation, etc.
3. Izbor načina
