Let two real valued functions f and g be defined as f(x) = sin x , x belongs to R and g(x) = tan x ; x belongs to R-{(n+1/2)pi} 1. fundamental period of fog(x)2. fundamental period of gof(x)3 range of gof(x)
In case of f(g(x)) period is = period of g(x) that is the inner fn. Now for sin(tanx) is 2π and for tan(sinx) is also 2π and its range is (-tan(1), tan(1)) please do approve my answer if correct
