 You are not required to do these on graph paper. Just make good legible sketches. For question 11, part (c), you may have to make a table of values for tan 3x, just like we did in class and then figure out the period for the tangent function when it undergoes a horizontal stretch or compression. It does not quite work the same way as the sine and cosine periods.

# 8 - 27

{Some of these can be challenging, but do the best you can and attempt all of them.There are cases such as question 25 where you will need to remember the two other identities we derived based on the pythagorean identity.}

#1, 3 a-b-c-d-h, 4 a-b-e, 7, & 9

[In question 3, when they say "state the corresponding range of y, they mean the range of the outputs or the interval between the minimum and maximum values. Also, for question 7, you may want to draw accurate sketches on graph paper as you will have to rely on those sketches for what is being asked.]

#2, 3, 4, 6 & 7.

Note: In many of the questions you will be required to apply what you already know in new situations. Do not forget the basics and in any circumstance, try something before coming on to the blog and asking a question. 

Homework Due 07/08/12

Folks, as I had instructed you in class. You will be graphing the sine, cosine and tangent functions by make a table of values with 15 degree increments for the inputs from -360 degrees to positive 360 degrees and then plotting them on the sheets I provided you in class. As some of you astutely pointed out that even with 30 degrees for one square we are two boxes short on each end. So, please take our rulers and pencils and extend the grid by two boxes before proceeding.

Also, write down any observations you have of the graphs you plot.

Note on the tangent graph :
This graph should leave you a little anxious as something will happen in its output values that you would not anticipate until you actually plot the graph. Do write down any special observation you have of this graph.

Classwork Continued...

You will continue the class work in your CW notebooks.

Summer Work

Okay folks, below are the exercises you have to complete over the summer, in addition to your exam corrections. You can do these questions on separate sheets of paper or in your H.W. journals. You will submit this work to me in our first class in August. You can use the blog post to discuss questions with me or with each other. Some of the questions will challenge and stretch your understanding. For many of you this is a great opportunity to learn and catch up with the rest of the class. Please don't try and do it all at the last minute!

[For question 28, you can use the software Graphmatica, which is 

a graphing software that you can download from http://graphmatica.com/]

[In these question when they say basic angle they mean the angle 

the star makes with the horizon line, no matter what quadrant it is in.]

Homework due Tuesday, 17/04/12

Folks, the following homework should basically be done without a calculator. You're going to be expected to use your understanding of logarithms and manipulate the expressions in order to find what is being asked.
