Refer to the on-screen indicators (e.g., DEG, RAD, GRAD) for the current angle unit. Press DRG► (accessed via 2nd F) to change the angle unit.
4.4 Scientific Functions
The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the 2nd F key first. Common functions include:
- Trigonometric: sin, cos, tan, and their inverse functions (sin-1, kos-1, beraz-1).
- Logarithmic/Exponential: log, ln, 10x, ex.
- Power/Root: x2, √, xy, y√x.
- Zatikiak: a b/c key for mixed numbers and improper fractions.
- Memoria: STO (store), RCL (recall), M+ (memory plus).
Consult the key labels and the calculator's display for specific function usage.
5. Mantentzea
5.1 Garbiketa
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing edo barne osagaiak.
