 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.

{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.}

[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.]

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.

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.
