adj = hyp * cos x. Substitute these values into equation (1) tan x = (hyp * sin x) / (hyp * cos x) Cancel out the common hyp term, and you have. tan x = sin x / cos x 分母不能等于0，当cosx=0时，tanx不存在。所以tanx=sinx/cosx 后面要加限制条件 x≠π/2+2kπ 2016-03-26 · sin(x)tan(x)+cos(x)=sec(x) sin(x)tan(x)+cos(x) = sin(x)sin(x)/cos(x)+cos(x) =sin^2(x)/cos(x)+cos(x) =sin^2(x)/cos(x)+cos^2(x)/cos(x) =(sin^2(x)+cos^2(x))/cos(x) =1 2018-03-26 · How do you simplify #cos x + sin x tan x#?
