4 5. My question is what does y mean in this case. The general rule for a reflection in the y -x.

We have a bunch of real points xy in the plane. What does delta x delta y mean in math. A variable doesnt have to be x it could be y w or any letter name or symbol.

That means you take the binary representation of x and y then or each pair of corresponding digits. A XOR B A B A B U2254 U003A U003D U2261 U003A U229C. The first x stands for all possible numbers in a set.

Any two of them satisfies the fact that a line drawn between them is fully inside this bunch of points. To reflect a point in the x axis multiply its y coordinate by -1. The letter x is often used in algebra to mean a value that is not yet known.

P Q means P is defined to be logically equivalent to Q. For example the slope of a line is y x ie. What does middle dot mean in algebra.

Im not saying its wrong but its unusual. A horizontal value on the x-axis. Xy has the meaning of a complex number.

In summary feel free to immediately use y instead of hx if it clarified the problem. The substitution is bad enough but using ys would make it worse. Denotes a quantity list set of coordinates or an.

It is called a variable or sometimes an unknown. X y over the x axis is now x -y If you come across the y already being a negative then make it a positive x. I dont know what is 2xy what does that mean.

X y z. When I think of yfx i Think of y fx 1 x 1 x 2 then y fx 2 x 3 then y fx3 and so on. Angles then it means angular minutes angular seconds.

But in elementary math texts x means the amount of change in the variable x. The composite functions of higher math often use hx and gx in combinationdefining which comes first and which is second. You will see that meaning of xy could be whatever of above.

Hi John I find it helps sometimes to think of a function as a machine one where you give a number as input to the machine and receive a number as the output.
