| April 17, 2021 | education
In trigonometry there is such a formula as the sum of the tangent and cotangent of the same chile is equal to one. It is derived and proved as follows.
tgx = sinx / cosx;
ctgx = cosx / sinx;
Hence tgx + ctg x = 1. The domain of definition and value in this case is all rational numbers.
Answer: y = tgx + ctgx = 1
