Introduction to online stress function polar coordinates tutor:
The stress polar coordinate system can be a 2-dimensional coordinate system. Stress in polar coordinates in which every point over a line or plane should be found out by between the distances from a fixed point to an angle from a fixed direction. Stress is the indispensable part of polar coordinates. The Displacements and stresses must be autonomous of angular location (θ) and there can be no twist (v θ must be zero).

The Tutor vista is one of the famous online web quest tutorial centers, in tutoring the tutor and the students can be communicated through the chat and help the audio from that the student clarifies (his/her) doubts. In the tutor vista online web quest tutorial canter tutoring is relates help to an academics subject like math, science and English or test preparation.
*
The fixed point (Equivalent to the source of the Cartesian or rectangular coordinate system) is known as the pole.
*
The rays from the poles over the fixed directions are known as polar axis.
*
The distance from the pole is called as the radial coordinate or radius in the system.
*
The angles should be the angular coordinates or polar angles.
*
The polar coordinates r and θ are specified in the terms of Cartesian coordinates by x = r cos θ
y = r sin θ
Here,
r = radius distance between the origin.
θ = the x-axis is counterclockwise angle.
*
The radius r in the terms of x and y will be,
r = √ (x2 + y2)
θ = tan-1(y/x)

1) Solving the subsequent rectangular coordinates to polar coordinate (3.5, 4.5)
Solution:
Given rectangular coordinates(x, y) = (7.8, 4.5)
R2= 7.82+4.52
R2= 60.84+20.25
R2= 81.09
R=9.004
q =tan-1 [(y/x)]
q = tan-1 [(4.5/7.8)]
q = 29.98°
The polar coordinates defined the (9.004, 29.98°)
2) Solving the subsequent rectangular coordinates to polar coordinate (1.5, 5.5)
Solution:
Given rectangular coordinates(x, y) = (1.5, 5.5)
R2= 1.52+5.52
R2= 2.25+30.25
R2= 32.5
R=5.7
q =tan-1 [(y/x)]
q = tan-1 [(5.5/1.5)]
q = 74.74°
The polar coordinates defined the (5.7, 74.74°)
Latitude is used to measure the distance north or south of the equator. Longitude is used to measure the distance east and west of the prime meridian. Latitude can simply be measured by measuring the height of the sun. The process of determining longitude is a much more complicated matter. One reason
In the case of using trigonometry to work out the height of the eucalyptus tree, we only need to use the tangent ratio in our formula because we have length of adjacent and we need to find the opposite length and the tangent ratio is opposite/hypotenuse. The formula itself is; Tan(θ) x adjacent = opposite.

Stress is a normal physical response to events that make you feel threatened or upset your balance in some way. When you sense danger—whether it’s real or imagined—the body's defenses kick into high gear in a rapid, automatic process known as the “fight-or-flight-or-freeze” reaction, or the stress response.
as the “r-value” and “r” can be any value between -1 and +1. It can be
Stress can be defined in two forms, Eustress and Distress. Eustress is a positive form of stress for the human body, it motivates and helps the body to focus on the task at hand. Distress on the other hand, is a negative form of stress and can cause anxiety, decreases performance, and makes it difficult for one to be motivated.
Stress is the combination of psychological, physiological, and behavioral reactions. Most people have a response to events that challenge or threaten them. Stress good and bad. Good stress is called eustress.

So what is stress? Stress is a normal physical response that happens when you feel threatened or upset. When you feel that you are in danger whether it is real or imaged. Your body has a response when stress occurs and it is a way of actually protecting you. Many times, stress helps people stay more focussed and energetic. Although, there is a point where stress can be very harmful and causes damage to your health in many aspects.
The plural of focus is foci. The midpoint of the segment joining the foci is called the center of the ellipse. An ellipse has two axes of symmetry. The longer one is called the major axis, and the shorter one is called the minor axis. The two axes intersect at the center of the ellipseThe center of the ellipse is at (h, k). The radius of ellipses are not a constant distance from the center. To find the distance to the curve from the center you have to find the distance from the center to the curve for the x and y separately, these points are called vertices. The vertices are on the major axis and minor axis. The major axis is the longer axis and the minor axis is the shorter axis through the center of the ellipse. To find the distance from the center in the x direction you take the square root of a2. To find the distance from the center in the y direction you take the square root of b2. You then will have two points on the x direction and two points in the y direction and you use these four points to draw your ellipse. Ellipses are symmetrical across both of there
