Given that the radius of earth is approximately 3950 miles, and it takes 24 hours to the earth to revolve once, compute, a) The angular velocity of a person standing on the surface of earth in rad per hour. b) The linear velocity of a person standing on the surface of the earth in miles per hour. (Round to nearest whole number.)

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.
