x = A sin â¡ ( Ï [ t â K ] ) + b , {\displaystyle x=A\sin(\omega [t-K])+b\ ,}. 1  A is the amplitude (or peak amplitude), 2  x is the oscillating variable, 3  Ï is angular frequency, 4  t is time, 5  K and b are arbitrary constants representing time and displacement offsets respectively.
Modeling agency. A modeling agency is a company that represents fashion models, to work for the fashion industry. These agencies earn their income via commission, usually from the deal they make with the model and or the head agency. The top agencies work with big-budget advertising agencies and fashion designers.
