History Log
Powerful, Precise, and Packed with Features
⚙️Complete Scientific Suite
Go beyond basic math. Our TI-30Xa tool provides a full array of scientific functions, including trigonometric (sin, cos, tan), logarithms (log, ln), powers, roots, and reciprocals. Everything you need for science and engineering coursework is at your fingertips.
💾Robust Memory Functions
Handle complex, multi-step calculations with ease. Our tool includes a fully functional memory bank. Store values (M+), subtract from memory (M-), recall the stored value (MR) for use in new equations, and clear it when you're done (MC). An 'M' indicator on screen lets you know when a value is stored.
💎Precision and Control
From parentheses for defining the order of operations to a full-featured `DRG` key for switching between Degrees and Radians, this tool gives you complete control. Keyboard support and an easy-to-use interface mean you spend less time clicking and more time solving.
Mastering Your Online Calculator
1. Entering Expressions
Simply type your calculation as you would write it. For example, to calculate 5 * (10 + 2), press the corresponding keys. The full expression is visible on the display, so you can verify your input before hitting the '=' key.
2. Accessing 2nd Functions
To use functions written in orange text above a key, first press the `2nd` key. The key will turn green to show it's active. For example, to find the square root of 9, press 2nd, then the x² key (to activate √), followed by 9, and finally ) and =.
3. Using Memory and History
After getting a result, press `M+` to add it to memory. To use that value later, press `MR`. To see a log of your recent calculations, press the `Hist` button. You can click any entry in the history log to bring the original expression back to the input screen for editing or recalculation.
