How to Enter Answers in WeBWorK Be careful entering powers of trigonometric, and other, functions. You write (sin(t))^2 for the square of sin(t), and never sin^2t. For example, 2+3sin^2(4x) is wrong. You should enter: 2+3*(sin(4*x))^2. Why does the last expression work? Because things in parentheses are always done first [ i.e. (4*x), and You can express integer literals with a binary format with a 0 followed by a B or b followed by a series of zeros and ones, for example: >>> 0b0010101010 170 >>> 0B010101 21 From the Python 3 docs , these are the ways of providing integer literals in Python: Express your answer as a chemical symbol or as an ion.
