What do the letter x and y stand for?
X and Y do not stand for anything. They are merely letters that represent a variable in an algebraic equation. X is generally used as the first variable, and Y is used as the second variable, to differentiate the difference between two variables so one letter does not need to be used for two variables. In GRAPHS, they stand for the axis line. X is the horizontal axis, and Y is the vertical axis.
What is the value of sin theta?
You cannot answer that until you assign theta a value. Theta is just a Greek letter that represents a variable, much like how we use English letters x,y, etc. to represent our variables.The reason the Greek letters are more appealing is that there are more Greek letters than English letters. So when working with complex equations that require many variables, it's more convenient to use the Greek alphabet.
What do the variables stand for?
Variables are letters that stand for numbers x=5 y=3 j=4 J+X = 9
Which of the letters is least like the other four T X L V Y?
The letter 'Y' is least like the other four, because it is the only vowel of the group.
What does Y plus 2D equals T mean?
It is a formula that links three variables: Y D and T together. It is not possible to impute any greater meaning without information on what the three letters stand for!
