![]() 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.
