A search light projected from a stationary helicopter that is hovering 1 mile directly over a bank is following a robber as he escapes from the bank. When the robber is 2 miles from the bank (assuming the road from the bank is straight), the search light is rotating at a rate of 0.5 radians/sec in order to keep up with the robber. How fast is the robber driving away from the bank? Don’t worry too much about how realistic your answer is.
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.
