\lambdaThe Greek letter lambda (\lambda) is commonly used in mathematics and science to represent a variety of concepts, including eigenvalues in linear algebra, wavelength in physics, and the rate parameter in exponential distributions in statistics.
Eigenvalue equation in linear algebra, where \lambda represents the eigenvalue.
Ax = \lambda xEquation relating energy (E) and wavelength (\lambda) in physics, where h is Planck's constant.
E = h \cdot \lambdaProbability density function of an exponential distribution, where \lambda is the rate parameter.
f(x) = \lambda e^{-\lambda x}
