Homework Tasks for EE 2320-001

You must "log in" to access your homework tasks. When you request a task for the first time, the system generates a set of task parameters applicable only to your instance of the task; although all students may be attempting the same task, each student will see different parameters applicable only to their task instance. Your task parameters are "saved" under your user name so that you will see the same parameters whenever you log in subsequently and request that task. When you submit your answer(s), they are "checked" and you are advised whether/not your submitted answer(s) are correct. You may repeatedly attempt the task until all your answer(s) are correct. Your submitted answer must be within +/- 1% of the correct answer to have the homework task counted as correct.

Some homework tasks feature multiple "parts" (multiple answers). You must submit correct answers for ALL parts of a multiple part task to obtain credit for the task.

A task's score is either 0% or 100%. The task's score remains 0% until the first time you submit correct answer(s), at which time the task's score becomes 100%. Once you have achieved a 100% score, that value will not subsequently change, even if you later re-attempt and submit wrong answers. Many students find it useful to revisit and re-attempt tasks (for which they have already received credit) at a later time to review their understanding.

Some homework tasks are simple enough that you can solve them and submit answer(s) while "on-line". Others may require more time and effort, in which case you may wish to print the homework task statement before you leave the site, solve the task off-line, then log-in again to submit your answer(s) for checking. You can then request another task to solve.

There is currently no penalty for multiple attemts with incorrect answers. However, you are strongly encouraged to make no more that four attempts before seeking assistance, otherwise you are simply wasting the precious resource of your time.

If you are currently enrolled (Spring 2019) in EE 2320-001 at The University of Texas at Arlington, these tasks are your homework tasks for part of your course grade.

"Scientific Notation" for Very Large/Small Numbers

Most exercises on this homework task site have answers dimensioned to be between 1 and 1000. E.G., suppose a current is requested in milliamperes: a text label "mA" will be displayed to the right of the answer box; if the answer is "50 mA", one would enter only the two integer digits "50" in the answer box. However, some answers are either very large/small numeric values. In such cases, "scientific notation" is required for the system to accept an answer. One example, suppose the number of electrons passing a point in a circuit is calculated to be 40 × 1023, one would enter "40E23" where "40" is the scientific notation "mantissa" and "23" is the scientific notation "exponent". Another example: suppose a component's power is requested in Watts and is calculated to be -75.2 microwatts: one would enter "-752E-7" in the answer box. The letter "E" indicates to the server programming that scientific notation is being employed.

It has been observed that server programming may fail to recognize (as a correct answer) a character string involving both a sign character and a radix point character "."; therefore, employ scientific notation.

When is homework "due" to remain current with lecture topics?

The "Lecture & Assignment Schedule" lists suggested dates by which homwork task sets should be more or less complete if we remain "on schedule".

When is homework "due" for course grade?

On the date of the semester's last exam at the time the exam begins. Prior thereto, there is currently no time-related penalty applicable to task completion. This means you have the entire semester to solve tasks for a grade.
