First draw a Cartesian plane. This is a plane with two axes on it: a horizontal line which is referred to as the x-axis and a vertical line, the y-axis. The two axes meet at the origin, O, which represents the ordered pair (0, 0). Measure out numbers on the x-axis according to some scale and do the same on the y-axis. These scales can be different.For each ordered pair, (p, q), start from the origin and move p units to the right (along the x-axis) and q units upwards (along the y-axis). The end point is the plot of that ordered pair, (p, q). Repeat for other pairs and, if required, join these points together.--------There are also quite a few videos on youtube.com that explain the concepts involved. I've put the URL for one of them in the link. If you would like to explore other youtube videos just do a search for ordered pair.
Q
Q-point means motionless point. At operating point the transistor emitter current and collector current doesn't change. That is why operating called as a quiesent point (q-point)
A Cartesian plane is a 2-dimensional, flat surface. The plane has two mutually axes that meet, at right angles, at a point which is called the origin. Conventionally the axes are horizontal (x-axis) and vertical (y-axis) and distances from the origin are marked along these axes. The position of any point in the plane can be uniquely identified by an ordered pair, (p, q) where p is the distance of the point along the x-axis (the abscissa) and q is the distance of the point along the y-axis (the ordinate).
If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
depending on the graph where point Q was you would not be able to tell where point Q ended after the rotaion finshed
2•(p-q)
nine plus q is in words. 9 + q is in numbers.
If (p, q) is any point on the line, then the point slope equation is: (y - q)/(x - p) = 2 or (y - q) = 2*(x - p)
selection of q-point is necessary in amplifiers,because if the q-point is not in the middle of load line the output may be clipped i.e not in the power supply range.
Irrational numbers. A good example of this is pi. If you were to write out pi as a decimal, the digits after the decimal point would go on forever.
Q point is also called operating point.Q point is mainly adjusted in transistors to make it stable. i.e., to operate the transistor in safe mode. Depending up on the operating current and voltage Q point is adjusted. The Q point defines the operating condition of the transistor and the transistors which quiescent point is adjusted are denoted as Q1,Q2.........Qn
