# Does Tan equal Y X?

The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. Like we have for the sine and cosine.

## What is a simple bar graph?

A simple bar chart is used to represent data involving only one variable classified on a spatial, quantitative or temporal basis. In a simple bar chart, we make bars of equal width but variable length, i.e. the magnitude of a quantity is represented by the height or length of the bars.

## What is the 1st quadrant in a graph?

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 the upper left-hand corner of the plane.

## Where is CSC negative?

Therefore, cosecants of the angles: that end in quadrants I and II are positive; that end in quadrants III and IV are negative.

## Is Tan positive quadrant 4?

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. In the fourth quadrant (IV), cos (and sec) are positive.

## Which quadrants are positive or negative?

Four Quadrants

Quadrant | X (horizontal) | Y (vertical) |
---|---|---|

I | Positive | Positive |

II | Negative | Positive |

III | Negative | Negative |

IV | Positive | Negative |

## What’s the middle of a graph called?

origin

## How does a bar graph look like?

A bar graph is a graph with rectangular bars with lengths and heights proportional to the values that they represent. On one axis of the graph, it shows the data categories that are being compared. The other axis represents the values corresponding to each data category.

## What are the 4 quadrants?

The coordinate axes divide the plane into four quadrants, labelled first, second, third and fourth as shown.

## Is Quadrant 3 positive or negative?

In Quadrant I, both the x– and y-coordinates are positive; in Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative.

## How do I edit a bar graph in Google Docs?

## What is cast rule?

The CAST rule is a special rule used often as a memorization acronym in trigonometry. Starting in quadrant 4 and going in a counter clock-wise fashion, the CAST rule will tell us what trigonometric ratios (cosine, sine, and tangent) are always positive in said quadrants.

## Where is sin cos and tan positive?

In the first quadrant, the values for sin, cos and tan are positive. In the second quadrant, the values for sin are positive only. In the third quadrant, the values for tan are positive only. In the fourth quadrant, the values for cos are positive only.

## What is the reference angle for 63 degrees?

Since 63° is in the first quadrant, the reference angle is 63° .

## What side of the graph is negative?

That means left is the negative direction for run. A way to remember this is to think about the numbers are on the x-axis. Going to the right of the origin are the positive values, and going to the left of the origin are the negative values.

## What is the quadrant in math?

Most commonly used in mathematics to refer to the four quarters of the coordinate plane. Recall that the coordinate plane has an x-axis that divides into a top and bottom half, and a y-axis dividing into the left and right half.

## Which quadrants on a graph are negative?

The upper-left quadrant, or Quadrant II, identifies only points to the left of zero (negative) on the x-axis and points above zero (positive) on the y-axis. Thus, any point in the second quadrant will be negative at the x value and positive at the y value.

## Which quadrants are which in a graph?

The first number in an ordered pair is the x-coordinate. The second number is the y-coordinate. The coordinate axes divide the plane into four regions called quadrants. The quadrants are numbered I, II, III, and IV as shown on the grid below.

## Why is tan positive quadrant 3?

for angles with their terminal arm in Quadrant III, since sine is negative and cosine is negative, tangent is positive. for angles with their terminal arm in Quadrant IV, since sine is negative and cosine is positive, tangent is negative.

## What quadrant would degrees be in?

Quadrants & Quadrantal Angles Angles between 0∘ and 90∘ are in the first quadrant. Angles between 90∘ and 180∘ are in the second quadrant. Angles between 180∘ and 270∘ are in the third quadrant. Angles between 270∘ and 360∘ are in the fourth quadrant.
