{"version":"1.0","type":"link","title":"Cofunction - Newikis","description":"In mathematics, a function f is cofunction of a function g if f(A) = g(B) whenever A and B are complementary angles (pairs that sum to one right angle). This definition typically applies to trigonometric functions. The prefix \"co-\" can be found already in Edmund Gunter's Canon triangulorum (1620).","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://thumb.wikimedia.org/wikipedia/commons/thumb/7/71/Sine_cosine_one_period.svg/1280px-Sine_cosine_one_period.svg.png","thumbnail_width":1280,"thumbnail_height":512}
