The function f(x)=x+cos x is

Consider the function f(x)= x cos x - sin x , then identify the statement which is correct

The value of b for which the function f(x)=x+cos x+b is strictly decreasing over R is: a) b =1

The value of b for which the function f(x)=x+cos x+b is strictly decreasing over R is: a) b =1

Consider the function f(x)=x cos x-sin x Then identify the statement which is correct.f is neither odd nor even.f is monotonic decreasing at x=0~ f has a maxima at x=pif has a minima at x=-pi

The primitive of the function f(x)= x | cos x| , when pi/2 lt x lt pi is given by

The function f(x) = x + cos x + b is strictly decreasing over R then:

For the function f(x)=x "cos" 1/x, x ge1

Range of the function f(x)= x cos( 1/x), xgt1

If the function f(x) = ( cos ( sin x ) - cos x )/( x^(4)) is continuous at each point in its domain and f(0) = ( 1)/( K ) , then k is "_______________" .

The set of points where the function f(x)=|x-2| cos x is differentiable is
