# What quadrants are sine in?

## What quadrants are sine in?

Sine and cosecant are positive in Quadrant 2, tangent and cotangent are positive in Quadrant 3, and cosine and secant are positive in Quadrant 4.

## What is the pattern of sine graph?

The graphs of sine and cosine have the same shape: a repeating “hill and valley” pattern over an interval on the horizontal axis that has a length of . The sine and cosine functions have the same domain—the real numbers—and the same range—the interval of values .

What are the parts of a sine curve?

Midline, amplitude, and period are three features of sinusoidal graphs.

### In what quadrant is sine positive?

It means: In the first quadrant (I), all ratios are positive. In the second quadrant (II), sine (and cosec) are positive. In the third quadrant (III), tan (and cotan) are positive.

### How do you find the value of sin?

The sin formula is given as:

1. sin θ = Perpendicular / Hypotenuse.
2. sin(θ + 2nπ) = sin θ for every θ
3. sin(−θ) = − sin θ

Where is the 4th quadrant on a graph?

bottom right corner
Quadrant IV: The fourth quadrant is in the bottom right corner. X has positive values in this quadrant and y has negative values.

## What are the 5 key points when you graph the sine function?

They are the three x-intercepts, the maximum point, and the minimum point. All of these are on your unit circle. The values of sin x correspond to the y-values, so those key points are (angle, y-value) or (0,0), (π/2, 1), (π, 0), (3π/2, -1), (2π, 0).

## How do you find the sine graph?

To find the equation of sine waves given the graph:

1. Find the amplitude which is half the distance between the maximum and minimum.
2. Find the period of the function which is the horizontal distance for the function to repeat.
3. Find any phase shift, h.

How do you write a sine function?

A general sinusoidal function is of the form y=A\sin(B(x-h))+k or y=A\cos(B(x-h))+k. Use the sliders in the applet to change the values of A,\ k,\ h, and B to create the functions in the table. Then describe the effect that changing each parameter has on the shape of the graph.

### How do you find the parts of a sine function?

A sinusoidal function is a function using the sine function. The basic form of a sinusoidal function is y = A sin (B(x – C)) + D, where A is the amplitude or height of our function, B is the change in period defined by 2pi/B, C the horizontal shift, and D the vertical shift.

### What are the different quadrants of the sine function?

These are sine, cosine, tangent, cot, sec, and cosec. Each of them have different values in the quadrant. In the first quadrant and the second quadrant, the sine function has positive values in the graph. This function records negative values in the third and fourth quadrant.

How do you label the quadrants of a graph?

How do you label the quadrants of a graph? The quadrants are labelled starting in the upper right and going counter-clockwise as Q I, Q II, Q III, and Q IV The quadrants are numbered (usually using Roman Numerals) in the sequence in which they occur for angles in standard position:

## What are the 4 graph quadrants of the plane?

The 4 Graph Quadrants. There are four graph quadrants that make up the Cartesian plane. Each graph quadrant has a distinct combination of positive and negative values. Quadrant I: The first quadrant is in the upper right-hand corner of the plane. Both x and y have positive values in this quadrant. Quadrant II: The second quadrant is in

## What is Quadrant 2 on a graph?

Quadrant II: The second quadrant is in the upper left-hand corner of the plane. X has negative values in this quadrant and y has positive values. Quadrant III: The third quadrant is in the bottom left corner.
