The right hand derivative of f(x) = [x] `tanpix` at x = 7 is (where [.] denotes the greatest integer function)

The right hand derivative of f(x)=[x]t a npix a tx=7 is (where [.] denotes the greatest integer function) 0 b. 7pi c. -7pi d. none of these

If f(x) =2 [x]+ cos x , then f: R ->R is: (where [ ] denotes greatest integer function)

Let f(x) = [x]^(2) + [x+1] - 3 , where [.] denotes the greatest integer function. Then

Let f(x)=[|x|] where [.] denotes the greatest integer function, then f'(-1) is

If f(x) =[ sin ^(-1)(sin 2x )] (where, [] denotes the greatest integer function ), then

If f(x)=([x])/(|x|), x ne 0 , where [.] denotes the greatest integer function, then f'(1) is

If f(x) = log_([x-1])(|x|)/(x) ,where [.] denotes the greatest integer function,then

Draw the graph of f(x) = [x^(2)], x in [0, 2) , where [*] denotes the greatest integer function.

f(x) = 1 + [cosx]x in 0 leq x leq pi/2 (where [.] denotes greatest integer function) then

Period of f(x) = sgn([x] +[-x]) is equal to (where [.] denotes greatest integer function
