This website is your “one-stop shopping” for all matters related to our class. Please check for the post of the day every time we meet!
Here is the news from the first day:
You should have received a copy of my course policies with the instructions for WeBWorK on the other side. If you were absent or loose them ever, they are available as pages here on this blog. (Follow the links.)
Our course textbook is available at this link (which is also in the updated course policies page): there are several formats available, including interactive graphics, which might be useful!
Here are the topics of the day: to be updated when I have time. Quick run-through now.
• Antiderivatives and indefinite integrals
This should be review from MAT 1475, but also take the opportunity to think more deeply about the concepts here.
An antiderivative of a function f(x) is basically another function whose derivative is f(x). We often call the antiderivative F(x), which requires distinguishing upper-case from lower-case. It’s annoying. A better notation is to subsume all the antiderivatives into one, called the indefinite integral.
A theorem of calculus tells us that once we have one antiderivative of f(x), all the others are found by adding an arbitrary constant, called the constant of integration.
So all we need to do is to find one antiderivative F(x), and the we know that the indefinite integral of f(x) is
where 
In practice, antiderivatives are used to solve differential equations, which are equations where we do not know a function but we know one of its derivatives. In order to find out the constant or constants of integration, we need some other information, which is usually called initial values or boundary values.
Homework:
• Find and deal with your City Tech email: you must use this email address in WeBWorK and to join the Piazza discussion board. Also, City Tech is already sending you emails here!
• WeBWorK has been set up for this course. The WeBWorK is here.
Please follow these instructions: MAT1575 WeBWorK information, in order to log in. After changing your password and entering your citytech email, you may start on the Orientation assignment to get used to how WeBWorK works.
A common problem that occurs when people try to log in using iPhone is that there is automatic capitalization for the first letter when you type in your username or password. Check to make sure the capitalization is turned off (or turn it off) while you type!
AFTER you’ve done at least 7-8 of the Orientation problems, you should start on the assignment which is due by Sunday evening 11 PM. Don’t wait to the last minute!
• Join the Piazza discussion board for this course by following this link. You will need to enter your City Tech email in order to join. I will post extra credit questions here from time to time!
• Also don’t forget the extra practice problems from the textbook. See the Course Outline for section 5.1: course outline here:MAT1575
See you on Wednesday!
