Homework Assignments:

Homework will be assigned on WebAssign every week, mostly on Friday.

Log-in Directions:
You will be required to set up your own account using the "class key" that I will give you in class. Go to WebAssign. Click on the Log In link on the right hand side of the page. Click on the I Have A Class Key link. The Class Key is composed of three fields. In the first field you will enter the word iit (lower case) followed by two four digit numbers unique to your section. Click Submit. If the information about your section is correct, click Yes, This Is My Class. At this point, follow the instructions to create a username and password. Once your account is set up, you will not have to use the Class Key again.
You will be given a grace period of approximately 14 days from the first day of classes to access WebAssign before you need to purchase your account online.

Important Advice for Homework:
You should first attempt each assigned problem on paper like regular paper and pen assignments (log off the WebAssign website). Save this written work for review before quizzes and exams. and in case you have to discuss your solution with me. Instructor cannot help you if you don't record your work carefully on paper when you need help from him.

Carefully read the WebAssign Student Guide to understand how to format your solutions.

When you have finished entering your answers, click on "Submit" and WebAssign will immediately grade your solutions. You can then re-work your incorrect problems and re-submit them to improve your score. You can submit your assignment up to 5 times without penalty.

After two incorrect attempts, look at the book again, review your notes and re-do the problem from scratch. Do not guess an answer. Remember you have only 5 attempts for each problem, so do not waste your attempts on frivolous trial and error solutions.

Do not enter an equivalent expression when your answer is marked wrong. x*(2*x-5) is the same as (2*x-5)*x, changing from one form to another will not change the validity of your answer. The software behind Webassign matches equivalent expressions, so do not send an email to your instructor that "WebAssign is marking your correct answer wrong". Its extremely rare for such errors to occur.

Avoid simple mistakes like: wrong syntax; incorrect usage of parentheses, x*(2*x-5) is not the same as x*2*x-5; using the incorrect letter for a parameter or a variable in a symbolic solution.

If you have technical difficulties with the WebAssign website, please contact their technical support directly online.

Homework Solutions will be visible soon after the due time. Use these solutions to prepare for the in-class quiz on Friday (next day). Especially note the way of writing and describing the solutions. I use the same descriptive details when I solve examples in class, so pay attention in class also.
For the quizzes and exams, you need to be able to describe the intermediate steps/ calculations/ substitutions for the solution. Just writing the final answer without justifying it will lead to deduction of points.
