Why are tide graphs sinusoidal?
Well, I don't think they're exactly sinusoidal, but yes, they do go up and down with a constant period. The reason they do that is that the force of the moon's gravity on any particular location on earth follows a regular pattern of increas... Read More »

What is the amplitude of the sinusoid's graph?
The sine wave varies from [-1,1]. Since there is a (-4) multiplier this is then scaled to [-4,4]. The amplitude is 4. The total displacement is twice the amplitude or 8 (4-(-4)). Read More »

The easiest thing to do is to scale it such that the ticks are every pi/4, up to 2pi. That will give you plenty of points.

You need to think back to the generation of a sine wave using a unit circle which has its center at the origin. Then as the angle increases from 0˚ rotating counter clockwise the points on the unit circle form right triangles. The sine func...

The period of a function is the time it takes to repeat itself. For normal sinusoidal graphs y=sin(x), y=cos(x), the period is 2pi. For y=tan(x) the period is pi. Lets take the example y=sin(x). If you were to modify it to be y=sin(2x). It ...

The function has an average. Let this be where y is 0. The function needs to start at 0 to be a true sin() function, so subtract the first place that the function is 0 from the graph. After converting the function so that the average is 0,...

You are right, both are "horizontal squiggly lines", however I think the sine function is the basic "squiggly line" but a sinusoidal equation can be a more complicated "squiggly line". Not sure what your level of math is but the basic sine ...
