This right- or left-shifting is called "phase shift". You've already learned the basic trig graphs. Because this 4 is subtracted from the tangent, the shift will be four units downward from the usual center line, the x -axis. Content Continues Below. Lissajous Figures Feedback? This relationship is always true: If a number D is added outside the function, then the graph is shifted up by that number of units; if a number D is subtracted, then the graph is shifted down by that number of units. The amplitude is given by the multipler on the trig function. For this function, the value of the amplitude multiplier A is —2so the amplitude is: 2.

The Sine Function has this beautiful up-down curve which repeats every degrees. Thus, the period of the sin, cos, csc, and sec graphs is 2\pi radians, and the period for the tan and cot graphs is \pi radians. Because the trig functions are cyclical. those graphs.

Learn how to construct trigonometric functions from their graphs or other features.

The graphs of sine, cosine, and tangent. Learn. Graph of.

For this function, the value of the amplitude multiplier A is given by 0. Biorhythm Graphs 7.

## Graphs of trigonometric functions Trigonometry Math Khan Academy

However, they do occur in engineering and science problems. Click to search:. The amplitude has changed from 1 in the first graph to 3 in the second, just as the multiplier in front of the sine changed from 1 to 3. This relationship is always true: Whatever number A is multiplied on the trig function gives you the amplitude that is, the "tallness" or "shortness" of the graph ; in this case, that amplitude number was 3.

Graph of y = sin ax. Graph of y = cos x. Graph of y = tan x.

## Graphs of Sine, Cosine and Tangent

The period of a function. The period of y = sin x. This section describes the graphs of trigonometric functions. The effect of q is called a vertical shift because the whole sine graph shifts up or down by q units. For q>0, the .

The maximum value of y=cosθ is 1 and the minimum value is −1. You've already learned the basic trig graphs. This function has a period of 2π because the sine wave repeats every 2π.

### Graphs of trigonometric functions

What is the period of f(t) = cos(3t)?.

This number is subtracted from the variable, so the shift will be to the right. More info: Trigonometry videos. So there will be a "gap" in the function at that point.

Putting it all together in terms of the sine wave, we have the general sine function:. An asymptote is a straight line that the curve gets closer and closer to, without actually touching it. I could also have used the simpler method, directly from the formula, of dividing C by B.

If we continue our table, we will get similar values because this is a periodic graph.

Do you see that this second graph is three times as tall as was the first graph? Consider the denominator bottom of this fraction.

In the sine wave graphed above, the value of the period multiplier B was 2. Phase shift or phase angle?

This gap is called a discontinuity.
