How are the graphs of sine and cosine related to the properties of the unit circle?
Suppose the radius of a unit circle makes and angle, q, which is measured in an anti-clockwise direction from the positive horizontal direction (so that East = 0 degrees, North = 90 degrees and so on.
Consider the x and y coordinates of the point on the radius, at the circumference of the unit circle, as the angle of the radius changes.
It can easily be shown with a couple of very simple diagrams (which I cannot do on this browser!) that
x = sin(q) and y = cos(q).

What is are the differences between circle graphs line graphs and bar graphs?
Circle graphs show data in a circle, while line graphs are akin to join the dots, and a bar graph shows data in vertical or horizontal bars, but all three show the same data results.
What kinds of graphs will best represent a given set of data?
circle graphs
How do you analysis a circle graph?
Analysis a circle graph through graphs and sociograms, Kinds of graphs, level of measurement, Each sector represents a part of the whole or circle is then split into parts,or sectors.
What can be inferred from the information in the two circles graphs?
This question cannot be answered without the circle graphs provided.
How are bar graphs line graphs and circle graphs used?
bar graphs are used to compare different data. a line graph is used to see the changes over a period of time of a specific data. a circle graph is used to represent a part to a whole relationship.
What is the difference between negative sine and cosine graphs and positive sine and cosine graphs?
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
How are bar graphs and line graphs and circle graphs different?
circle graphs add up to 100% , bar and line graphs don't
What Tree types of graphs to display data?
line graphs, bar graphs,and circle
What type of graphs are used for qualitative observations?
circle graphs
What is are the differences between circle graphs line graphs and bar graphs?
Circle graphs show data in a circle, while line graphs are akin to join the dots, and a bar graph shows data in vertical or horizontal bars, but all three show the same data results.
How are circle graphs line graphs and bar graphs different?
a circle graph is in a circular form and represents your data using pieces inside of itbar graphs represents data using bars
How are bar graphs and circle graphs the same?
They both progression up or down
What kinds of graphs will best represent a given set of data?
circle graphs
What are 2 graphs that compare 2 sets of data?
Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.
How do circle graphs hep compare different groups of data?
Circle graphs, or pie charts compare the percentage of different things.
Are circle graphs different than pie charts?
yes because pie charts are out of 360 degrees and circle graphs are out of 100%
How do you analysis a circle graph?
Analysis a circle graph through graphs and sociograms, Kinds of graphs, level of measurement, Each sector represents a part of the whole or circle is then split into parts,or sectors.
