All rights reserved.By Sharon K. This is an exploration for Advanced Algebra or Precalculus teachers who have introduced their students to the basic sine and cosine graphs and now want their students to explore how changes to the equations affect the graphs. This is an introductory lesson whose purpose is to connect the language of Algebraic transformations to the more advanced topic of trignonometry. A key follows the end of the exploration. Consider the basic sine equation and graph.

If the first function is rewritten as…. Take a look at the blue and red graph and their equations. The graph of the first function remains in black. Equation of blue graph. Equation of red graph. Describe how the equation of the first function has changed to become the equation of the graphs in blue and red. This value is called the amplitude of the graph. Describe how the graph of the first function has changed to become the blue graph and the red graph.

Be as specific as possible.

Trigonometry Examples

Include in your answer how a specific point on the graph of the first function transforms to become a point on the blue graph and on the red graph. Take a look at an animation of this phenomenon.

Click here …. Be patient. These movies take awhile to load…. Now consider the purple and green graph and their equations. Equation of purple graph. Equation of green graph. Describe how the equation of the first function has changed to become the equation of the graphs in purple and green. Describe how the graph of the first function has changed to become the purple graph and the green graph.

Include in your answer how a specific point on the graph of the first function transforms to become a point on the purple graph and on the green graph. Look deeper than horizontal versus vertical…. Take a look at this phenomenon…. Examine the purple and green graph and their equations. Describe how the graph of the first function has changed to become the red graph and the green graph.

See how it moves…. Consider the blue and purple graph and their equations. This value is called the phase shift of the graph. Describe how the equation of the first function has changed to become the equation of the graphs in blue and purple.

Students will need to match one from each category together: 1.Each year my Pre-calculus students first encounter the graphs of sine and cosine curves, I find two groups of learners in my room.

I also found the spaghetti activity already created in paper and pencil format at NCTM Illuminations. You can download your copy HERE. To begin graphing and translating graphs for Sine and Cosine functions this year, I had my students complete this page in their interactive notebooks.

Both the sine function and the cosine function need 5-key points to complete one revolution. There is a starting point and a stopping point which divides the graph into four equal parts. I want them to learn the positive A-value patterns for the 5-key points of each function. Now, for the real test. When it comes time to translate these functions with phase shifts, horizontal and vertical transformations, reflections, along with all four values A, B, C, and D in the standard form equation, I want my students to develop some procedural techniques for themselves to better understand how easy these graphs can be sketched.

Patience and practice are the key. I have my own personal procedural techniques that I model for my students prior to asking them to create their own step-by-step approach. If so, sketch that line and label it x- prime. Once they get the five key points plotted, the last thing to do is to connect the points with a smooth curve and then repeat the pattern if you want them to sketch two full periods of the function.

Instead, it is a composition of all the colors of the rainbow in the form of waves.

The individual colors can be seen only when white light passes through an optical prism that separates the waves according to their wavelengths to form a rainbow. Light waves can be represented graphically by the sine function.

In the chapter on Trigonometric Functionswe examined trigonometric functions such as the sine function. In this section, we will interpret and create graphs of sine and cosine functions. So what do they look like on a graph on a coordinate plane? We can create a table of values and use them to sketch a graph. Plotting the points from the table and continuing along the x -axis gives the shape of the sine function.

Again, we can create a table of values and use them to sketch a graph. Because we can evaluate the sine and cosine of any real number, both of these functions are defined for all real numbers. Now we can clearly see this property from the graph. Again, we determined that the cosine function is an even function.

As we can see, sine and cosine functions have a regular period and range. If we watch ocean waves or ripples on a pond, we will see that they resemble the sine or cosine functions. However, they are not necessarily identical. Some are taller or longer than others. A function that has the same general shape as a sine or cosine function is known as a sinusoidal function.

The general forms of sinusoidal functions are. Looking at the forms of sinusoidal functions, we can see that they are transformations of the sine and cosine functions.
