Cosine squared minus one
WebSo the object is rotating in the positive direction as t increases. If the object were rotating clockwise (negative angle), then the equations of TIME would read. x = 3 cos (-t), y = 2 sin (-t) And now as time moves forward, the object rotates clockwise (negative angle). This example can be a bit confusing because the parameter could be angle. WebJan opens a stock account with $5,000 at the beginning of January and subsequently deposits$200 a month. Unfortunately, the market is depressed, and she finds that t months after depositing a dollar, only 100f(t) cents remain, where f (t) = e − 0.01 t. f(t)=e^{-0.01 t}. f (t) = e − 0.01 t. If this pattern continues, what will her account be worth after 2 years?
