Best ResponseYou've already chosen the best response.0general equation of a simple harmonic oscillator is Asin(wt). where A is the amplitude and w is the angular frequency.. amd 2pi/w is the time period...

Best ResponseYou've already chosen the best response.0the equation you are giving should be a function of time and not distance... and by adding a minus sign you are just changing its phase by pi.

Best ResponseYou've already chosen the best response.0a. y = 3 sin (3x/2  3π/8) b. y = 3 sin (4x/3  π/3) c. y = 3 sin (4x/3  π/4) d. y = 3 sin (3x/2  π/4)

Best ResponseYou've already chosen the best response.1\[\huge y=a \sin(bxc)+d\]\[a=amplitude\]\[\frac{2\pi}{b}=period\]\[c=phase \; shift\]

Best ResponseYou've already chosen the best response.1Let's figure out our b term. \[\large \frac{2\pi}{b}=\frac{3\pi}{2}\]\[\large b=\frac{4}{3}\] I hope I calculated that correctly hehe

Best ResponseYou've already chosen the best response.1\[\large y=3\sin\left(\frac{4}{3}x\frac{\pi}{4}\right)\]

Best ResponseYou've already chosen the best response.1Mmmmm I'm not sure if I did that correctly, was I suppose to factor the 4/3 into the pi/4? I forget...

Best ResponseYou've already chosen the best response.1Yah I think the b is suppose to be like this... \[\huge y=a \sin (b(xc))+d\]

Best ResponseYou've already chosen the best response.1Which IS one of your options, if you distribute the 4/3 to the pi/4 term.

Best ResponseYou've already chosen the best response.1Hmm how did you arrive at your answer? :o

Best ResponseYou've already chosen the best response.0i think its b. y = 3 sin (4x/3  π/3)
