![]() Then the result is squared.) You can always use the Preview button to see a typeset version of what you entered and check whether what you wrote was what you meant. :-) The "sin" operation has highest precedence, so it is performed first, using the next token (i.e. (You can enter it as sin(t)^2 or even sint^2, but don't try such things unless you really understand the precedence of operations. You can enter sin^2(t) as a shortcut although mathematically speaking sin^2(t) is shorthand for (sin(t))^2 (the square of sin of t).For example, sin 2t is interpreted as sin(2)t, i.e. Write sin(t) instead of sint or sin t even though WeBWorK is smart enough to usually accept sin t or even sint. It's always good practice to use parentheses when entering functions. Entering big quotients with square brackets, e.g.Parentheses: () - You can also use square brackets,, and braces, 's (except in contexts where those have special meanings, like creating intervals or sets). ![]() ^ or ** You can use either ^ or ** for exponentiation, e.g.* Multiplication can also be indicated by a space or juxtaposition, e.g.Mathematical Symbols Available In WeBWorK 6.1 Exponential and Logarithmic Functions.6 Mathematical Functions Available In WeBWorK.4 Scientific Notation Available In WeBWorK.3 Mathematical Constants Available In WeBWorK.1 Mathematical Symbols Available In WeBWorK.
