Math 124 Name _______________#2 TRIGONOMETRY [PART I] 1.51. Consider the standard sine function. What is the period, amplitude, and average value?2. Consider the transformation sin( )y A Bx C D where , , ,A B Cand D are positive constants. Explain how the value of these constants affects the graph of the standard sine function.3. The following function describes the relationship between air temperature in Fairbanks, Alaska as a function of time. (National Weather Service).2( ) 37sin 1.7386 25365T t t A. Without graphing this function, determine its period, amplitude, and average value.B. Graph one period of this function. Label appropriate values on the axes. 3. The rate of intake during a respiratory cycle (liters/sec) for a person at rest is proportional to a sine wave with period six seconds. Suppose the rate is 0.85 liters/sec when 1.5t sec.A. Find an equation that describes the rate of intake as a function of time.B. Graph one cycle of your equation. Which part corresponds to inhaling? Exhaling? Explain.TtMath 124 Name _______________4.
