# Applications of sine and cosine graphs in real life worksheet

The unit circle has a circumference of C = 2π r = 2π(1) = 2π. Therefore, if a point P travels around the unit circle for a distance of 2π, it ends up where it started. In other words, for any given value q, if 2π is added or subtracted, the coordinates of point P remain unchanged (Figure 1).. Figure 1 Periodic coterminal angles.

Since we are going to look at sinusoidal functions in context, I want to get students thinking of different real-life situations where a sine or cosine graph would be applicable. With their groups, ask students to brainstorm different real-world situations in which a sine or cosine graph would be a good model. Possible Ideas Students will suggest:
You will also find a step-by-step video to help you get started. The problems get increasingly difficult and there are two (2) problems for each difficulty and one (1) for you to try on your own. The application problems show different ways that one could use sine and cosine funtions in real life.

Two great law of sines problems. These two law of sines problems below will show you how to use the law of sines to solve some real life problems. Problem #1 Two fire-lookout stations are 15 miles apart, with station A directly east of station B. Both stations spot a fire.

Apr 22, 2019 · Graphing Sine and Cosine Functions. Recall that the sine and cosine functions relate real number values to the $$x$$- and $$y$$-coordinates of a point on the unit circle. So what do they look like on a graph on a coordinate plane? Let’s start with the sine function. We can create a table of values and use them to sketch a graph.
