Calculus in a notebook

Use the written page for reasoning and Research → 2D Graph for visual checks. Type a complete expression such as y=sin(x) or insert a definite integral from the Math keyboard.

Try this workflow

1. Open the notebook and write the question in text and math.
2. Open Research, choose 2D Graph, and add y=sin(x).
3. Use the measure controls for a definite integral. Positive and negative contributions are shown separately while the signed result remains preserved.
4. Copy the research snapshot to a page for an editable, printable record.

What is verified

Supported function values, derivatives, sums, products, matrices, and definite integrals are evaluated locally where the engine has a defined method. Incomplete or unsupported expressions are reported instead of silently producing a graph.
