Oops!

Yesterday, I was actually asked for Law of Sines problems!  So, here you go...

I will also try to put some work up for identities, review problems, and so on, but I make no promises.

Trig Identity Problems

I was asked to post more trig identity problems.  Here's a nice looking worksheet I found on-line.

Test # 2 Review

I was asked for more problems to practice in preparation for the test tomorrow.  See the following.  I will try to put some answers up tonight, but it will probably be late (and I've got to watch America's Got Talent!).

More ITF and Graphing Practice

Students have asked me today for more practice (I love it!!!).  I said I'd put these up on the blog.  Read carefully...

Here is Inverse Trig Functions practice, as requested by 2nd period students.

Here is Trig Graphing practice, as requested by a 1st period student.


























(If you turn in one of these, I will give you bonus on Monday's or Tuesday's quiz for each correct answer... Shhhhhhhh, don't tell, but tell people to look at the blog!)

More Trig Graphs!

Here's a few more trig graphs to practice with one, two, or three transformations.  I will hopefully have some hard copies before the day is out, if you'd like to pick one up.

New Trig Graphs with 1 Transformation

This is a link to the graphs we worked on at the end of class today.  Please be comfortable with these by Tuesday so we can start graphing with multiple transformations.

Have a great 3-day weekend!

Test # 1 Reviews

Tomorrow, Tuesday, 8/27, is our first test in Math IV and Accelerated III.  Today in class we worked on a Test Review and a 20-problem graphing worksheet.  I believe I have successfully saved these worksheets in such a way that you can access the worksheets and the solutions (which are at the end of the document).  Feel free to check your work, and send me an email if you have questions.  I will likely be in access of my email most of the night.

Good luck in your studies.  Don't forget the Unit Circle!
