1. need a flow chart that's explains step by step how to determine the exact value of all the primary and reciprocal trigonometric ratios for some angles between 0 and 2 pie. concepts you may want to include are how to sketch an angle. The cast rule. Special triangles. And example.
2. a person who was listening to a serum notices that the frequency fluctuated with time, measured in seconds. The minimum frequency was 500 HZ and the maximum frequency was 1000HZ. The maximum frequency occurred at t=0 and again every 3 seconds. What is the equation of the coding function that describes the frequency of this siren?
3. owen is jumping on a trampoline. When his feet hit the deck of the trampoline, the metrical depresses to a minimum height of 2cm. On average Owen is reaching a maximum height of 200 cm every 10 seconds. Determine the equation of a sinusoid also function that would model this situation, assuming Owen reaches his first maximum at 6 seconds.
4. the water at a local beach has an average depth of one meter at low tide and an average depth at 8m high tide. One cycle of the tide takes approximately 12 hours. This periodic motion can be modeled by the function d(t)=3.5cos pie/6 t + 4.5 where d(t) represents the depth of the water in meters at a time t in hours. The equation assumes that the water level is at high tide at time zero. Many people dive into the water from a nearby dock. If the water must be at least 3m deep to dive safely when during the daylight hours would it be safe to dive of the dock?
5. without graphing determine the average rate of change for the function f(x)=x^4 on the intervals: -1< x<1, -2
