A plane flies at a speed 540 km/hr at a constant height of 10 km. How rapidly is the angle of elevation to the plane changing when the plane is directly above a point 145 km away from the observer? The angle of elevation is changing at ______ radians/hr (enter a positive value).
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.
