What is De Moivre’s Theorem? De Moivre’s theorem can be used to find powers of complex numbers How do I use de Moivre’s Theorem to raise a complex number to a power? If a complex number is in Carte...
Simple Reflex Arc A reflex response (also known as an involuntary response) does not involve the conscious part of the brain as the coordinator of the reaction Awareness of a response having...
The First Law of Thermodynamics The First Law of Thermodynamics, which is based on the principle of conservation of energy, states: The internal energy of a system is increased when energy i...
Internal Energy Energy can be classified into two forms: kinetic or potential energy The molecules of all substances contain both kinetic and potential energies Kinetic energy is due to the ...
Resonance The frequency of forced oscillations is referred to as the driving frequency (f) or the frequency of the applied force All oscillating systems have a natural frequency (f0), this i...
Free & Forced Oscillations Free Oscillations Free oscillations occur when there is no transfer of energy to or from the surroundings This happens when an oscillating system is displaced ...
What are complex roots? A quadratic equation can either have two real roots (zeros), a repeated real root or no real roots This depends on the location of the graph of the quadratic with respect to...
