If `f(x)=cos{pi/2[x]-x^3}, 1

If f(x)=(sqrt(cos((pi)/(2)-x)))/(1-cos(x+(pi)/(2))^((1)/(3))) and g(x)=(1)/(sqrt([sin x])) then range of g(x)-f(x) contains

If f(x)=cos[pi/x] cos(pi/2(x-1)) ; where [x] is the greatest integer function of x ,then f(x) is continuous at :

If f(x)=cos[pi/x] cos(pi/2(x-1)) ; where [x] is the greatest integer function of x ,then f(x) is continuous at :

If f(x)=cos[pi/x] cos(pi/2(x-1)) ; where [x] is the greatest integer function of x ,then f(x) is continuous at :

If f(x)=cos[pi^2]x+cos[-pi^2]x then the value of f(pi/4)+f(pi/2) is

If f(x)=cos[(pi)/(x)]cos((pi)/(2)(x-1)); where [x] is the greatest integer function of x, then f(x) is continuous at :

If f(x)=3+cos^-1(cos(pi/2+x)cos(pi/2-x)+sin(pi/2+x)sin(pi/2-x)) , x in [0,pi] then find the minimum value of f(x) is

If f(x)=cos^-1(sin(4cos^2x-1)), then 1/pif'(pi/3).f(pi/10) is

If f f(x)=cos[pi^2]x+cos[-pi^2]x where [x] stands for the greatest integer functions, then evaluate f(pi/2),f(pi),f(-pi), andf(pi/4) .
