In this problem, you will be a math detective! Some of the symbols and functions may not be familiar to you, but with a little digging, reading, and observing, you'll be able to figure them out. Your task is to simplify the following expression as much as possible, without using a calculator (either hardware or software). Do not approximate. Express all values as integers (not decimals) and all rational numbers as improper fractions. S(n) -(6) 9 S(n) = symbolic expression Symbolic General format information: Your answer must be a symbolic expression. All numbers must be rational - so, 1/2 instead of 0.5. Complex numbers are not allowed. Allowable variables, constants, and operators: n pi e cos sin tan arccos arcsin arctan acos asin atan arctan2 atan2 explog sort O + 7 A ** All operations must be explicit: Example valid inputs: 2*3 cos (1) Example invalid inputs: 2(3) COS 1 Note that either or can be used for exponentiation
