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.
A senior make-up artist on an advertising shoot can earn Â£500 per day. Top make-up artists can earn about Â£3,000 a day designing make-up for fashion shows. Agencies arrange such jobs but charge the artist up to 20% commission. Film work can pay from Â£500 to Â£800 a week. Theatrical work, which can range from face make-up to wig care, pays about the same depending on the job.
