The fx-50FH II is powered by a twin power system (Solar cell + 1x LR44 alkaline button battery). If the screen text dims even in well-lit environments, replace the internal LR44 battery by unscrewing the back panel cover. Always perform a full memory reset ( SHIFT -> 9 -> 3 ) after changing the battery.
Slide out the old LR44 battery and insert a new one with the positive (+) side facing up.
The fx-50FH II is highly capable of running statistical analyses for single or paired variables. Single-Variable Statistics (SD Mode) Press [MODE] →right arrow [4] (SD).
Geometric calculations like the cosine formula and triangle area.
Press SHIFT MODE (SETUP). Then press 3 for Deg (degrees), 4 for Rad, or 5 for Gra. For HKDSE math, you almost always need Deg. casio fx50fh ii manual
