Math Assignment| May 11 2012 | | 1) Is the family relationship amongst hours of twenty-four hour period and twenty-four hour period of year cyclic in nature? guarantee your answer. Yes, the relationship between hours of daylight and day of year periodic is in nature. It is because there are 365.25 years in peerless year and four years for wizard period which nub there are firing to run four said(prenominal) data in the whole period. And there is going to arrive at the very(prenominal) maximum and minimum for four times. Therefore, this relationship is a periodic. 2) employ the represent intend the brings (a) Amplitude= (Max. - Min. )/2 = (15.45- 8.95) /2 = 3.25 (b) menstruation= 360 (c) Phase liberation= vertical reflection, vertical stretched by agentive role of 3 (d) exposition= 12.2 units upward (3) Given your answer from 2. Determine the par of the honeyed line in the form: (a) f(x)= a sin k ( x -d ) +c f(x)= 3.25sin(1/2x)+8.96 (b) f(x) = a cos k ( x d ) +c f(x)= -3.25cosx+ 12.2 (4) Entering the conniption used: X min. = 0 X max. = 375 Y min. = 0 Y max. = 16 (5) The equation occurred in the graphing ready reckoner is 3.232 sin (0.17x+1.38) +12.

17 (6) The figurer provide only do sinusoidal regression in radians. To alternate your equation to degrees, take your b (or k) subject and quadruplex it by 180/?. Answer: 180/? for both equations. In degrees, it is 57.3. (7) How does your graph compare with your data generated graph on the cal culator? State any similarities or differenc! es using name from this unit. The law of similarity between my graph and the data generated graph is both of them have the same y- interrupt which is 8.96. And, my cosine function is exactly the same with the data generated graph. However, my sine functions maximum value is not 15.45 but 12.2. Heres the difference between my sine function and the data generated graph. (8) Using both equations, determine the expected hours of daylight...If you want to get a full essay, hunting lodge it on our website: OrderEssay.net
