Question

why there are only six trigonometry ratios??​

Answer 1

Answer:

Answer : The 6 trigonometric ratios are formed by taking all the possible ratios of the any two sides of a perpendicular triangle out of three sides

Answer 2

Answer:

The historical answer: At least 12.

There are at least six more trigonometric functions that at one time were considered worth naming. These are versine, haversine, coversine, hacoversine, exsecant, and excosecant. All of these can be expressed simply in terms of more familiar trig functions.

The 6 trigonometric ratios are formed by taking all the possible ratios of the any two sides of a perpendicular triangle out of three sides.
