You should input your answer into the answer box below the question prompt. Depending on the question, you may need to enter a numerical answer, a function/expression in terms of variables/constants provided by the question, or some exact text.
The input field can function like a mini-calculator; it understands common constants and functions. It will show you a preview of your parsed answer as you type, and will display an approximation of your answer when the answer is an exact number.
In fact, if your answer does not have an exact decimal representation, you must type in the exact answer (in terms of \(\cos, \sin, e, \pi, \text{etc.}\)). The precision used your answer is checked to is greater than that of most calculators. For example, if the answer is \(e^{\cos 2}\), you must not enter your answer as 0.65958, but instead something like e^cos(2).
The functions you may use can be found here: functions, constants. Not all of these will work in the input field, but simple elemetary functions and common constants should work. To use \(\pi\) for example, simply type pi. To calculate \(\cos(1)\), simply enter cos(1). Note that all trigonometric and hyperbolic functions use radians as both of their input and output units.
The following manually added / renamed functions are also available:
If you use undefined constants or functions, it may not error until you submit your answers at the end, which is when answers are checked.
It should be clear from context what type of answer you need to give. The questions give you enough information to discern whether the answer is in terms of constants and variables from the question, or whether it is a numerical value.
Your answers will be saved between sessions.
Apart from the tutorial questions, your answers will not be checked as
you type them. This is to prevent brute-forcing the answer to each
individual question. Moreover, the system is designed so that it can only
tell if
However, if there is an error evaluating a certain answer you inputted, then you will be told which question that was so you can correct it.
