A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...

Scatter diagrams are used to explore patterns between two sets of data. The table shows the results of eight students' maths and science marks in an assessment. Construct a scatter graph that ...

The sum of the probabilities of all outcomes is 1. Independent events are those not affected by a previous event. The probability of two independent events both happening is 𝑃(A and B) = 𝑃(A) × 𝑃(B ...

This file type includes high-resolution graphics and schematics when applicable. Beam diagrams are used as a fundamental way to teach engineers the basic of static loading. Beams are structural ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
