Calculate current in parallel circuits, voltage in series circuits, and resistance in both series and parallel configurations. Use Ohm's Law, DC calculations, and LR filter tools.
Generate random numbers between a set minimum and maximum. Set parameters for decision-making, game playing, or list selection. Output the result directly without additional steps.
Sketch graphs or input data points to generate formulas. Use finger painting or keyboard entry to define data series. The calculates fit formulas and trend lines using least squares regression. Export results and view statistical analysis.
