`f(x) = [sin x + [cos x + [tan x+ [secx]]]` Here `x in (0,pi/4)` Find range

f(x)=[sin x+[cos x+[tan x+[sec x]]] Here x in(0,(pi)/(4)) Find range

The range of f(x) = [ sin x+ [ tan x+ [secx ]]] , x in (0, (pi )/(4)) where [.] denotes greatest integer function is

The range of f(x)=[sin x+[cos x+[tan x+[sec x]]]],x in(0,(pi)/(4)), where [.] denotes the greatest integer function less than or equal to x is

Evaluate int_(0)^((pi)/(4)) [sin x + [cos x + [tan x + [sec x]]]] dx

Show that f(x)=tan^(-1)(sin x + cos x) is an increasing function in (0, (pi)/(4)) .

f(x)= |(sin x,cos x),(tan x,cot x)| then f'((pi)/(4)) = …….

If f'(x) = a sin x + b cos x and f'(0) = 4,f(0) = 3, f((pi)/(2))= 5 , find f(x).

Prove that f(x)=tan ^(-1)(sin x + cos x ),x gt 0 f(0,pi/4) is increasing function
