From now on: - write inline math formulas in this format: \( <latex code here> \) (never use dollar signs for inline math since it doesn't work here) - write full size math equations/formulas in this format: $$ <latex code here> $$ (don't forget newlines between the dollar signs and latex code) You should write your response with 200 or more words.
