Assume the smallest possible measured relief displacement on a vertical photo is 0.5 mm Is it possible to determine the height of the telephone kit imaged in a 23 cm square angle taken from a height of 900m above the ground? NB: the telephone utility box actually stands 1.2m above the ground
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.
