## Winston Scientific Calculator Description
Evaluate two expressions at the same inputs and inspect their sampled difference with an explicit angle convention.

HOW IT WORKS
1. Open Tools and choose Compare models.
2. Enter A(x), B(x), an increasing range, sample count and angle mode.
3. Compare the rows, inspect undefined results, save the latest worksheet or share the comparison.

The scientific calculator, graphs, Function Lab, matrices, conversions and number tools remain available.

WHAT TO KNOW
Supports 2–101 sample points and expressions up to 500 characters. Samples do not prove equality or exact intersections between points. Ans, memory and unspecified registers are not imported; use explicit constants for reproducibility. One worksheet is retained locally.

iPhone and iPad.
