Calculus I
2007 Paul Dawkins 1 http://tutorial.math.lamar.edu/terms.aspx
PrefaceHere are a set of problems for my Calculus I notes. These problems do not have any solutions
available on this site. These are intended mostly for instructors who might want a set of problems
to assign for turning in. I try to put up both practice problems (with solutions available) and these
problems at the same time so that both will be available to anyone who wishes to use them.
As with the set of practice problems I write these as I get the time and some sections will have
only a few problems at this point and others wont have any problems in them yet. Rest assured
that Im always trying to get more problems written but this site has been written and maintained
in my spare time and so I usually cannot devote as much time as Id like to the site.
ProductandQuotientRuleFor problems 1 7 use the Product Rule or the Quotient Rule to find the derivative of the given
function.

For problems 8 12 use the fact that ( )3 12f - = , ( )3 9f - = , ( )3 4g - = - , ( )3 7g - = ,
( )3 2h - = - and ( )3 5h - = determine the value of the indicated derivative.
