WebWhich equation would produce this sine graph? Possible Answers: Correct answer: Explanation: The graph has an amplitude of 2 but has been shifted down 1: In terms of the equation, this puts a 2 in front of sin, and -1 at the end. This makes it easier to see that the graph starts [is at 0] where . The phase shift is to the right, or . WebTo see how the sine and cosine functions are graphed, use a calculator, a computer, or a set of trigonometry tables to determine the values of the sine and cosine functions for a …

WebFinding features from graph Given the graph of a sinusoidal function, we can analyze it to find the midline, amplitude, and period. Consider, for example, the following graph. A … WebIf you start at the blue point this is a sine graph, as you are starting at the sinusoidal axis. y = 8+5 Sin (90°/7 (ϴ -3°)) But if you start at the green point this is a cosine graph, as you are starting at the maximum. y = 8+5 Cos … diatech streamer

WebTo stretch a graph vertically, place a coefficient in front of the function. This coefficient is the amplitude of the function. For example, the amplitude of y = f (x) = sin (x) is one. The amplitude of y = f (x) = 3 sin (x) is three. Compare the two graphs below. Figure %: The sine curve is stretched vertically when multiplied by a coefficient WebAnother way of thinking about the problem is to let z = cosα+ isinα. Then, using the fact that zn = 1, evaluate zn1 You should get that z1 = cosα −isinα. I could not make out how you arrived at that step. I'm posting here my answer. \begin {align*} 3 [\sin^4 (\frac {3\pi} {2}-a)+\sin^4 (3\pi+a)]-2 [\sin^6 (\frac {\pi} {2}+a)+\sin^6 (5\pi ... WebThe cosine rule is: \ (a^2 = b^2 + c^2 - 2bc \cos {A}\) This version is used to calculate lengths. It can be rearranged to: \ (\cos {A} = \frac {b^2 + c^2 - a^2} {2bc}\) This version is used to... citing a bible verse apa
