Trigonometric Ratios
By means of trigonometric ratios, one can obtain the value of two acute angles, and, of the right triangle.
Given the length of the hypotenuse and of a cathetus, the ratio is:
The trigonometric inverse function is:
in which is the angle opposite the cathetus .
The adjacent angle of the catheti, will be = 90° –
One may also obtain the value of the angle by the equation:
in which is the other cathetus.

Famous quotes containing the word ratios:
“Typography is not only a technology but is in itself a natural resource or staple, like cotton or timber or radio; and, like any staple, it shapes not only private sense ratios but also patterns of communal interdependence.”
