How the fuck am I wrong?

>>714439535
Amplitude should be 4, no?

>>714439726
this

>>714439535
by putting in the wrong answer maybe read the fucking graph

>>714439535
Amplitude is 8, peakpeak, and should be defined as +4/-4, meaning, if you want an amplitude of 2pp, you have to define +1/-1.

>>714439535
amplitude is 8, phase shift is pi/2

Amplitude is 4, I just wasn't paying attention.

People saying Amp is 8 I'm not sure what you're on about, you only count the amplitude once in a sinusoidal function. You're probably thinking of something else.

Also phase shift is in fact 0. You can clearly see it originating at 0. In a sinusoidal function the phase shift is wherever the function hits x while going upward.

It's a phase-shifted cosine you hugh fag

>>714439535
Op, people assuming an ac or signal. Mech engg here. could. be wrong.

Is that why the answer is correct?

What exactly are they asking here, what exact value?

I don't think it's radians or degrees. Do they mean the xy coordinates on the unit circle?

>>714441053
Answer is correct because the question really is, fit curve to A*sin(nx+c)

>>714441340
Radian

>>714441340
rt3/2 and -1/2. And why am I doing ur homework ?
