So for the first question that's visible on screen, i'm going to say the most likely the answer that they're expecting is true.
00:12
But there is a little bit of ambiguity.
00:16
The reason why i say there's a little bit of ambiguity is basically depends on what's meant by pre -established in this context.
00:23
So specifically, we have that an equation or a formula is any expression.
00:39
Which relates values.
00:48
So i could make up a formula, a equals b over c, and that is a valid formula.
00:57
Just depends on what a, b, and c are.
01:01
It might not be accurate, but it would be counted as a mathematical formula.
01:08
So it doesn't have to be written down by somebody else to be a valid mathematical formula.
01:14
But, generally speaking, the idea of saying a formula is another word for equation.
01:20
If that's effectively what you're meant to read from the statement, that statement would be true.
01:25
The second statement is false.
01:30
So, in a very theoretical sense, we have that an operator is something which acts upon an argument, or in the very theoretical sense, we have that an operator is a mapping...
