f(x)=cot^(-7)x+xquad " as "quad " ,"lag x=?

The interval in which f(x)=cot^(-1)x+x increases , is

The interval in which f(x)=cot^(-1)x+x increases , is

The interval in which f(x)=cot^(-1)x+x increases , is

Which of the following pairs of function are identical? a. f(x)=e^(In sec^(-1)x) " and " g(x)=sec^(-1)x b. f(x)=tan(tan^(-1)x) " and " g(x)=cot(cot^(-1)x) c. f(x)=sgn(x) and g(x)=sgn(sgn(x)) d. f(x)=cot^(2)*cos^(2)x " and " g(x)=cot^(2)x-cos^(2)x

The function f(x)=cot^(-1)x +x increases in the interval :

f(x)=cot^(2)x*cos^(2)x, g(x)=cot^(2)x-cos^(2)x then f and g are identical?

f(x)=cot^(2)x*cos^(2)x , and g(x)=cot^(2)x-cos^(2)x prove that f(x)=g(x)

f(x)=max{tan x,cot x)

If f(x)=tan^(-1)cot x, then
