I. Go to https://www.mathopenref.com/reference-angle.html and use this to calculate the reference angles for these three problems.
1) 250 2) 20 3) 470







II. Go to http://www.mathguide.com/cgi-bin/quizmasters/Trig1.cgi and do one problem.









III. Go to http://www.mathguide.com/cgi-bin/quizmasters/Trig3.cgi and do one problem.










IV. Go to http://www.mathguide.com/cgi-bin/quizmasters/Trig2.cgi and do one problem.














V. Go to http://www.mathsisfun.com/algebra/images/sine-graph.gif and review the graph. Answer these questions based on the graph of this sine curve. Keep in mind that the curve continues left and right forever, which makes the domain of the curve equal to (-infinity, +infinity).













1) Write the Range of this sine curve.


2) The sine curve repeats itself in a reoccurring pattern. Two cycles (patterns) are shown. What is the horizontal length of one cycle (pattern)?


3) Where does the sine curve intersect the y-axis? [This is called the y-intercept.]




VI. Go to https://www.technologyuk.net/mathematics/trigonometry/images/trigonometry_004
2.gif
and determine how the sine curve are similar and different.
