What is the graph for Y COSX?

What is the graph for Y COSX?

Graphing y = cos x In particular, y = cos x is periodic with period 2π . This means that if the point (x, y) lies on the graph, then the point (x+2kπ, y) will also lie on the graph where k is any integer.

What is the range of the functions y COSX and Y Sinx?

Note that the domain of the function y=sin(x) ) is all real numbers (sine is defined for any angle measure), the range is −1≤y≤1 . The graph of the cosine function looks like this: The domain of the function y=cos(x) is all real numbers (cosine is defined for any angle measure), the range is −1≤y≤1 .

What is the graph of cos theta?

To graph the cosine function, we mark the angle along the horizontal x axis, and for each angle, we put the cosine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. It is the same shape as the cosine function but displaced to the left 90°.

What is the difference between Y Sinx and Y COSX?

The sine and cosine functions have several distinct characteristics: They are periodic functions with a period of 2π. The graph of y = sin x is symmetric about the origin, because it is an odd function. The graph of y = cos x is symmetric about the y-axis, because it is an even function.

What is the relation between Y Sinx and Y COSX?

If the graph of y = cosx is translated π/2 units to the right, we get the graph of y = sinx. This means that the equation cos(x – π/2) = sinx is an identity. Alternatively, translating the graph of y = sinx π/2 units leftward yields the graph of y = cosx. So, the equation sin(x + π/2) = cosx is an identity as well.

What is the minimum value of Y for Y Sinx?

For y=sin(x), the maximum value is 1 and the minimum value is -1, so the amplitude of the above curve is 1. The Period: The period of the sin curve is how many radians it takes to complete one cycle, or the lengh of one cycle. For y=sin(x), the period is from x=0 to x=2pi.

What is the reciprocal of sin?

The cosecant ( csc ⁡ ) (\csc) (csc) The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

What is equal to Tanθ?

⇒ θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Hence, the general solution of tan θ = tan ∝ is θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Note: The equation cot θ = cot ∝ is equivalent to tan θ = tan ∝ (since, cot θ = 1/tan θ and cot ∝ = 1/tan ∝).

What is the period of y sin 3x?

So, the period of sin 3x is 2π/3 or 2/3 π.

What does the graph of a cosine function look like?

The graph of a cosine function y = cos ( x ) is looks like this: Properties of the Cosine Function, y = cos ( x ) . Domain : ( − ∞ , ∞ ) Range : [ − 1 , 1 ] or − 1 ≤ y ≤ 1

How to create a graph using Mathway and cos?

Find the vertical shift d d. List the properties of the trigonometric function. Select a few points to graph. Tap for more steps… Find the point at x = 0 x = 0. Tap for more steps… Replace the variable x x with 0 0 in the expression. Simplify the result.

What is the amplitude of y = cos ( x )?

The amplitude of the graph of y = a cos ( b x) is the amount by which it varies above and below the x -axis. The period of a cosine function is the length of the shortest interval on the x -axis over which the graph repeats. Sketch the graphs of y = cos ( x) and y = 2 cos ( x) . Compare the graphs.

How to graph the trigonometric function sin x?

Since the trigonometric functions repeat every 2π radians (360º), we get, for example, the following graph of the function y = sin x for x in the interval [−2π,2π]: To graph the cosine function, we could again use the unit circle idea (using the x-coordinate of a point that moves around the circle), but there is an easier way.
