WebThe range of f(x) = sin x and f(x)= cos x will lie from -1 to 1, including both -1 and +1, i.e.-1 ≤ sin x ≤1-1 ≤ cos x ≤1; Now, let us discuss the function f(x)= tan x. We know, tan x = sin x / cos x. It means that tan x will be defined for all values except the values that will make cos x = 0, because a fraction with denominator 0 is ... WebSlightly confusingly, the function tan(x) is considered continuous - more than bit continuous, because the asymptotes at x = pi/2 + n pi are rejected from to domain. graph{tan(x) [-10.06, 9.94, -4.46, 5.54]} Meanwhile, aforementioned sawtooth function f(x) = x - floor(x) is not considered piecewise steady as a function from RR to RR, but is … Web20 apr. 2024 · Show that f(x) = tan^(–1) (sin x + cos x) is a decreasing function on the interval (π/4, π /2). asked Apr 20, 2024 in Derivatives by Yajna ( 30.0k points) increasing and decreasing functions hulk clippers
