Graph of y=sin (x) - Khan Academy
See how we find the graph of y=sin(x) using the unit-circle definition of sin(x). The graph of y=sin(x) is like a wave that forever oscillates between -1 and 1, in a shape that repeats itself …

Graph sinusoidal functions (practice) | Khan Academy
Given the formula of a sinusoidal function of the form a*f(bx)+d, draw its graph.
Example: Graphing y=3⋅sin(½⋅x)-2 - Khan Academy
Sal graphs y=3⋅sin(½⋅x)-2 by thinking about the graph of y=sin(x) and analyzing how the graph (including the midline, amplitude, and period) changes as we perform function transformations …
Midline, amplitude, and period review - Khan Academy
Given the graph of a sinusoidal function, we can analyze it to find the midline, amplitude, and period. Consider, for example, the following graph.
Amplitude & period of sinusoidal functions from equation
Well, the easy way to think about it is just what is multiplying the cosine function. And you could do the same thing if it was a sine function. We have negative 1/2 multiplying it. So the …

Curvature of a helix, part 1 - Khan Academy
The way that we compute it is to first find the unit tangent vector function with the same parameter and what that means if you imagine your helix spiraling through three dimensional space. Man, …

How would you graph a trig function that has a constant in place of the y-value? In other words, if you take the graph of y = tan(x), and input a 3 for the y-value, what would the graph of 3 = …
