Frequently Asked Questions

Use the standard caret symbol ^ to process exponential values, mirroring the physical calculator's layout (e.g., typing x^2 fields for squaring coordinates or 3^4 structures for parsing higher-order variables).
he primary JavaScript math library structures interpret trigonometric values (sin, cos, tan) directly in Radians. To process angle parameters in Degrees, multiply your value parameters by (pi / 180) inside the input box.
This emulator handles complex scalar expressions, order calculations, and 2D function graphs. For high-level, multi-tiered square matrix matrices or custom structural cell arrays, combine arrays inside bracket delimiters matching standard programming languages.
If the tracking viewport appears empty, check your Window settings (Xmin, Xmax, etc.). If your function outputs large values (e.g., x^2 + 50), but your Ymax boundary is locked at 10, the plotted line will fall outside the visible viewport dimensions.
