Function Access (2nd F Key)

Many keys have secondary functions printed above them. To access these functions, press the 2nd F key first, then the desired function key. The "2nd F" indicator will appear on the display.

Example: To calculate sin(30):

1. Ensure the calculator is in DEG mode (see Display Modes).
2. Pịa 2nd F, mgbe ahụ mmehie (which is the primary function of the key).
3. Banye 3, 0, wee pịa =. Ngosipụta ga-egosi 0.5.

DeeView Ngosipụta

The DeeView feature allows you to input and display equations in a natural, textbook-like format.

• Enter equations as they appear in your textbook. The calculator will display fractions, roots, and other expressions clearly.
• Use the arrow keys (left, right, up, down) to navigate within an equation for editing.

Display Modes (DEG, RAD, GRAD)

The calculator supports three angle modes: Degrees (DEG), Radians (RAD), and Gradians (GRAD).

• To change the mode, press the MODE key repeatedly until the desired mode (DEG, RAD, ma ọ bụ GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

Ọrụ ebe nchekwa

The calculator includes memory functions to store and recall values.

• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Memory Minus): Subtracts the displayed value from the independent memory.
• RCL (Recall Memory): Recalls the value stored in the independent memory.
• STO (Store Memory): Stores the displayed value into a specific variable memory (A, B, C, D, E, F, X, Y, M).

Fractions and Decimals

• To enter a fraction, use the ab/c igodo.
• To convert a fraction to a decimal or vice versa, press the 2nd F igodo sochiri ya ab/c igodo.

Statistical Functions

The calculator includes various statistical functions.

• Ịbanye STAT mode, pịa MODE igodo rue STAT ahọpụtara.
• Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.
• Refer to the detailed function guide for specific statistical operations.
