A little help with exam style questions...

Exams start on Thursday, January 8. I will post some sites to help with some of the examples I will use in class during our review. This first one is how to use the completing the square technique t o identify conic sections (circles, ellipses, parabolas and hyperbolas) and if necesssary their key features.Click Here

You may want to jump to slide 66 to see the completing the square piece in action.

Another topic we started before break was linear programming and optimization. This link has some practice and hints. Linear Programming

Why logarithms are your friends.....

This next link is to Interactive Unit Circle. It demonstrates why sine and cosine graph the way they do.

Radians Refresher

If you are looking for a good review of radians and unit circle, here is the Khan Academy link you might find useful. Unit Circle with Radians

Trig Games

I've been trying persistently to add asterisks to the links for you to try but my laptop is being stubborn. One of the games you should try is the trig flash cards. You can choose to work with degrees or radians. I wouldn't choose the seccnat, cotangent or cosecant options until after we explain them in class.
