f(x)=x-ex+tan((2 pi)/(7))" is "

The domain of definition of the function f(x)=tan((pi)/([x+2])) , is

Period of the function f(x)=tan(nx)-pi cos((2 pi x)/(7))+(x)/(sin((2 pi x)/(7)))+11 is (where {.} is fractional part function)

The expression (tan(x-(pi)/(2))cos((3 pi)/(2)+x)-sin^(3)((7 pi)/(2)-x))/(cos(x-(pi)/(2))tan((3 pi)/(2)+x)) is equal to

f(x) = (1- tan x)/(4x-pi), x ne (pi)/(4) . If the function f(x), x in [0, (pi)/(2)) is continuous then find f((pi)/(4)) .

If f(x) = (1 - x) tan (pi x)/(2) then "limit"_(x->1) f(x) is equal to :

If f(x ) = (sin^(2)x)/(1+cot x) + (cos^(2))/(1+tan x) then f((pi)/(4)) is

The minimum value of the function tan(x+(pi)/(6))f(x)=(tan(x+(pi)/(6)))/(tan x) is:

f(x)=tan x,x in(-(pi)/(2),(pi)/(2)) and g(x)=sqrt(1-x^(2)) then g(f(x)) is

The function f(x)=((pi)/(2)-x)tan x is discontinous at
