Why cos x -1 has only one solution you mean cos x is -ve both in second and third quadrants but you are just going for second quadrant taking pie n proceeding?
I assume the question is about cos x = -1.
While it is true that cos x is negative in both the second and third quadrants, it reaches the value of -1 where the two quadrants meet, not inside the quadrants. The point where they meet is on the [negative] horizontal axis and x is -pi radians.
What else can I help you with?
What are the names of the quadrants on a graph?
The names of the quadrants on a graph are: First quadrant Second quadrant Third quadrant Fourth quadrant
What are the numbers of a quadrants?
In a Cartesian coordinate system, the plane is divided into four quadrants. The first quadrant (Quadrant I) is where both x and y coordinates are positive, the second quadrant (Quadrant II) has negative x and positive y values, the third quadrant (Quadrant III) has both coordinates negative, and the fourth quadrant (Quadrant IV) features positive x and negative y values. Quadrants are typically numbered counterclockwise, starting from the upper right.
How many quadrants in the cartesian plane?
The Cartesian plane is divided into four quadrants. These quadrants are determined by the signs of the x and y coordinates: the first quadrant (positive x, positive y), the second quadrant (negative x, positive y), the third quadrant (negative x, negative y), and the fourth quadrant (positive x, negative y).
What are the coordinates of a point that could be in each of the four quadrants?
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
How can the word 'quadrant' be used in a sentence?
The quadrant shaped piece of cake was delicious.
What are the quadrants in math?
There are four quadrants. They are represented by Roman numerals : I(one), II(two), III(three), IV(four). The first quadrant contains all positive points , (+x, +y) The second quadrant contains negative x's and positive y's , (-x, +y) The third quadrant is all negative , (-x, -y) The fourth quadrant has negative y's and positive x's , (+x, -y)
Is it possible for a line to pass through exactly two quadrants?
Yes, it is possible for a line to pass through exactly two quadrants. For instance, a line that has a positive slope can pass through the first and third quadrants if it extends from the second quadrant to the fourth. Similarly, a line with a negative slope can pass through the second and fourth quadrants. In both cases, the line does not intersect the axes in such a way that it enters all four quadrants.
One of the fourcardinal points of an astrological chart?
The cardinal points of a chart are the beginnings of each quadrant. the four quadrants are found by dividing the circle into hemispheres both vertical and horizontal. This give you 4 quadrants; each quadrant is further divide in to three houses the first being Cardinal, the second multiple, and the third succeeding. The 4 cardinal signs are Aries (fire) 1st house 1st quadrant, Cancer (water) 1st house 2nd quadrant, Libra (air) 1st house 3rd quadrant and Capricorn (earth) 1st house of the 4th quadrant.
Do x and y coordinates have opposite signs!?
Yes, x and y coordinates can have opposite signs. This occurs in the second and fourth quadrants of the Cartesian coordinate system. In the second quadrant, x is negative and y is positive, while in the fourth quadrant, x is positive and y is negative.
What are quadrants in a coordinate plane?
In a coordinate plane, quadrants are the four sections created by the intersection of the x-axis and y-axis. They are labeled as follows: the first quadrant (I) is where both x and y coordinates are positive, the second quadrant (II) has negative x and positive y coordinates, the third quadrant (III) features both coordinates as negative, and the fourth quadrant (IV) has positive x and negative y coordinates. This system helps in identifying the location of points based on their coordinates.
Why is the first quadrant the first quadrant?
It 2-dimensional coordinate geometry, angles are measured from the origin, relative to the positive direction of the x-axis and they increase in the anti-clockwise direction. As a result, small positive angles are in the first quadrant, and as the angle size increases it moves into the second, third and fourth quadrants.
Suppose you know that the sine of an angle is 0.8000 WHat is the angle?
To find the angle whose sine is 0.8000, you can use the inverse sine function (arcsin). The angle is approximately 53.13 degrees in the first quadrant. Additionally, since the sine function is positive in both the first and second quadrants, there is also a second solution: approximately 126.87 degrees.
