KọView Ifihan

KọView 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, tabi GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

Awọn iṣẹ iranti

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

• Láti tẹ ìpín kan, lo ìpín kan ab/c bọtini.
• To convert a fraction to a decimal or vice versa, press the 2nd F bọtini atẹle nipa awọn ab/c bọtini.
