## How do you know which quadrant is positive or negative?

Four QuadrantsIn Quadrant I both x and y are positive,in Quadrant II x is negative (y is still positive),in Quadrant III both x and y are negative, and.in Quadrant IV x is positive again, and y is negative..

## How do you know if a degree is positive?

Positive DegreeThe Positive Degree. The positive degree of an adjective or adverb offers no comparison. For example:The Comparative Degree. The comparative degree of an adjective or adverb shows the greater or lesser degree. … The Superlative Degree. The superlative degree of an adjective or adverb shows the greatest or least degree.

## Is Quadrant 4 positive or negative?

For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. Therefore: In Quadrant IV, cos(θ) > 0, sin(θ) < 0 and tan(θ) < 0 (Cosine positive). The quadrants in which cosine, sine and tangent are positive are often remembered using a favorite mnemonic.

## Which quadrant is the terminal side of an angle in?

Quadrant IIIf the terminal side of an angle lies “on” the axes (such as 0º, 90º, 180º, 270º, 360º ), it is called a quadrantal angle. The angle shown at the right is referred to as a Quadrant II angle since its terminal side lies in Quadrant II.

## What quadrant is the angle in?

An angle in standard position is said to lie in a quadrant if its terminal side lies in that quadrant. In the figures below, apha lies in the 1st quadrant, β lies in the 2nd quadrant, γ lies in the 3rd quadrant and θ lies in the 4th quadrant.

## What is a negative degree angle?

Term. Definition. Negative Angle. A negative angle is an angle measured by rotating clockwise (instead of counterclockwise) from the positive @$x@$ axis.

## How do you find a positive Coterminal angle?

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians . Example 1: Find a positive and a negative angle coterminal with a 55° angle.

## Why cosine of negative angle is positive?

Now the measure of the angle is -m, a negative value when measured clockwise is, because all angles have to be acute to apply the various trigonometrical ratios or relations. Hence, cosine of a negative angle changes into a positive value.

## What are the 4 quadrants?

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

## What is the standard position of an angle?

Angles can exist anywhere in the coordinate plane where two rays share a common vertex. If this vertex is at the origin of the plane and the initial side lies along the positive $x$-axis, then the angle is said to be in standard position.

## What is CSC of an angle?

In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc. csc θ = hypotenuse / opposite.

## How do you find negative angles?

For instance, the bottom part of the vertical line is 270°. When measured in the negative direction its will be -90°. We simply subtract 270 from 360. Given a negative angle, we add 360 to get its corresponding positive angle.

## Are negative angles acute?

There is some common terminology for angles, whose measure is always non-negative (see #Positive and negative angles): An angle equal to 0° or not turned is called a zero angle. Angles smaller than a right angle (less than 90°) are called acute angles (“acute” meaning “sharp”).

## Is Quadrant 1 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.

## What quadrant is sin positive and tan negative?

Quadrants and the “cast” Rule 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.
