sketch with axes and with a horizontal line (y=1) with a point in the first quadrant above this horizontal line, and a point in the fourth quadrant vertically below their first point.The two points do not need to be labelled, may be incorrectly labelled.The horizontal line should b...
A slight modification of the constants and a simple translation give a system of coordinates in which the first quadrant contains only greens, the second blues, the third purples and the fourth reds and yellows. The resulting diagram is compared with that obtained by MacAdam. Transformation ...
First quadrant: (+, +) Second quadrant: (-, +) Third quadrant: (-, -) Fourth quadrant: (+, -) In this case, + represents a positive real number while - represents a negative real number. 2. Find the x and y coordinates of the middle of the line connecting the points (5, -3...
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. ( x=4(cos)((π )/4)) ( y=(4)(sin)((7π )/4)) The exact value of ( (cos)((π )/4)) is ( (√2)/2). ( x=4((√2)/2)) ( y=(4)(sin)((7π )/4)) Cancel the...

Using the polar coordinates, evaluate int int e^{x^2+y^2} dy dx on the region enclosed by the circle, x^2+y^2=2. Use polar coordinates to evaluate the double integral over R of e^(x^2 + y^2) dA where R is the region in the ...
Coordinates are a pair of numbers which are used to determine the position of a point or a shape in a 2-dimensional plane. We define the position of a point on a 2D plane using two numbers, called the x-coordinate and the y-coordinate. The x-coordinate always comes first in the order...
In the first quadrant we have a quarter of a circle x^2+y^2=1 (radius = 1. In the second quadrant we have x^2+(y-0.5)^2=0.25 (radius=0.5). Then, since the function exists both in first and second quadrant, 0<=theta<=pi. Then, by my false reasoning, I made a mistake of...
