Answer 1

Answer:

Explanation:

n a course book I'm currently reading, the author uses notation typeset in LaTeX (or some other TeX flavour...) that I usually use when writing by hand, but never thought was possible with TeX: he "crosses out" terms in an equation with an arrow and the number 0, indicating that they go to zero and will be ignored.

For example, this notation is used when linearizing equation, to show which higher order terms are ignored in the coming analysis. It basically looks like a long, slanted arrow (a / with an arrowhead) that reaches from a little below the line to a little above the line, with the arrowhead upwards and a small 0 at the tip. I realize this description is pretty vague, but it's probably the best I can do without paint :P
