Two sides of a triangle have lengths 12 m and 15 m. Theangle between them is increasing at a rate of 2 0 / min . Howfast is the length of the third side increasing when the angle between the sides of fixed length is 60 degree ?
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.
