The square of this function appears multiplied by the incidentintensity to give the emitted intensity of a polarizer in (*) Malus' Law.
A spherical harmonic can be decomposed into N times an exponential times the associated Legendrepolynomial of THIS function. The wavelength shift in Compton scattering is equal to the Comptonwavelength times one minus this function. The square of this function appears multiplied by the incidentintensity to give the emitted intensity of a polarizer in (*) Malus' Law. This function appears on the top left andthe bottom right entry on the standard 2 by 2 rotation matrix. For a block on an incline, this function multipliedby the force of gravity gives the magnitude of the normal force. For two vectors, the dot product is equal to theirmagnitude multiplied by this function of the angle between them. For 10 points, name this function which is alsoused to find the x-component of a given vector.
