A rocket rising straight up into the air is being tracked by a radar station located 20 miles from the point on the ground directly below the rocket. When the angle of elevation (the angle between the horizontal and the line of sight to the rocket) is π/3, the angle is increasing at a rate of 0.05 radians per second. Find the velocity of the rocket at that instant (in miles per hour)
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.
