If `f(x) =cos [pi^(2)]x+ cos [-pi^(2)] x,` where `[x]` denots the greatest integer function, then the value of `f((pi)/(2))` is-

If f(x)=cos[pi^(2)]x+cos[-pi^(2)]x , where [x] stands for the greatest integer function, then

If f(x)= cos [ pi^(2)] x+ cos[ -pi^(2)] x where [x] denotes the greatest integer function, then show that f(-pi)=0

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

If f(x)= cos [ pi^(2)] x+ cos[ -pi^(2)] x where [x] denotes the greatest integer function, then show that f((pi)/(4)) =(1)/(sqrt(2))

If f(x)=cos[pi^2]x +cos[-pi^2]x , where [x] stands for the greatest integer function, then

If f(x)=cos[pi^2]x +cos[-pi^2]x , where [x] stands for the greatest integer function, then

If f(x)=cos([pi^2|x)+cos([-pi^2|x) , where [x] stands for the greatest integer function, then

If f(x)= cos [(pi^(2))/(2)] x + sin[(-pi^(2))/(2)]x,[x] denoting the greatest integer function,then

If f(x)= cos [(pi^(2))/(2)] x + sin[(-pi^(2))/(2)]x,[x] denoting the greatest integer function,then
