Limits of expressions involving the trigonometric functions can be evaluated by direct substitution --- unless division by zero is encountered. When division by zero is encountered, simplifications such as the ones presented in the Conceptual Understanding of Limits lesson can be attempted.
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an excessive electric current limited only by the Thevenin thÃ©venin equivalent resistance of the rest of the network and potentially causes circuit, damage, overheating fire or. explosion
Explanations > Power > Soft Power. Soft power is not... | Soft power is... | The power of soft power | The long game | So what? When we talk about power, we can consider it as somewhere on a spectrum from 'soft' to 'hard'. But what does this metaphor mean? Soft power is not... It can be quite difficult to define soft power, possibly because it is a subtly force. A soft way of defining it is to start with what it is not. Hard power. Hard power is, at the hardest, about physical coercion.
