WebTo write a sine function you simply need to use the following equation: f(x) = asin(bx + c) + d, where a is the amplitude, b is the period (you can find the period by dividing the absolute value b by 2pi; in your case, I believe the … 1) All of the functions are of the form, {eq}y=A\cos(Bx+C)+D{/eq}, and all of the functions have the same {eq}B{/eq} value of {eq}2{/eq}. The period of a cosine function is given by {eq}\dfrac{2\pi}{ B }{/eq}, so all four functions have a period of {eq}\dfrac{2\pi}{2}=\pi{/eq} 2) 3) All of the graphs are similar … See more In the video lesson we learned that for a cosine function {eq}f(x)=A\cos(Bx+C)+D{/eq}, the period of the cosine function is {eq}\dfrac{2\pi}{ B }{/eq}. … See more Consider the functions: {eq}f(x)=\cos(2x)\\g(x)=3\cos(2x)\\h(x)=\cos(2x+\pi)\\j(x)=\cos(2x)-1{/eq} 1) What is the period of these functions? 2) Graph … See more 1) What will the graph of {eq}g(x)=4\cos(3x-4)+1{/eq} look like compared to the graph of {eq}f(x) = \cos(3x){/eq}? 2) What are the periods of these functions? 3) … See more For a function of the form, {eq}f(x)=A\cos(Bx+C)+D{/eq}, the number, {eq}A{/eq}, vertically stretches the graph of {eq}\cos(Bx){/eq} by … See more is beavercreek in dayton
How to Find the Amplitude and Period of the Cosine Equation
Webperiod 2π/B = 2π/4 = π/2. phase shift = −0.5 (or 0.5 to the right) vertical shift D = 3. In words: the 2 tells us it will be 2 times taller than usual, so Amplitude = 2. the usual period is 2 π, but in our case that is "sped up" … WebFind Amplitude, Period, and Phase Shift y=cos(x) Step 1. Use the form to find the variables used to find the amplitude, period, phase shift ... Amplitude: Step 3. Find the period of . Tap for more steps... The period of the function can be calculated using . Replace with in the formula for period. The absolute value is the distance between a ... WebThe period of the cosine function in its basic form, y = \cos (x) y = cos(x), is 2π. This period can be modified by multiplying the variable x by a constant. We can reduce the period of … one good hand poker
