You can drag the terminal point in the applet below to adjust the openness of the given angle. As you drag the point, the angle's measurement in radians (0) will be shown. 0 = 0.01 By using the applet above, fill in the table of values below. cos(0) 2 1.57 2 T= 3.14 37 2 4.71 27 = 6.28 Now, sketch a graph of h = cos(0) based on the information in the table above. h

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
