\varOmega

The Greek letter Omega (\varOmega) is often used in mathematics and science to represent a variety of concepts, such as the set of all possible outcomes in probability, the last element in a sequence, or angular velocity in physics.

Examples

Represents the sample space in probability theory, which is the set of all possible outcomes.

\varOmega = \{ \omega_1, \omega_2, \ldots, \omega_n \}

Denotes the limit of a sequence, often used to represent the last or ultimate value.

\varOmega = \lim_{n \to \infty} a_n

Represents angular velocity in physics, where \theta is the angle of rotation.

\varOmega = \frac{d\theta}{dt}
