Find the value of `a` for which the function f(x)=cos(x)-sin(x)+a(x)+b is decreasing. Find the value of `a` for which the function f(x)=cos(x)-sin(x)+a(x)+b is decreasing.
we know that f(x) is decreasing for all real values of x if f'(x)<0f'(x)=-cosx-sinx+a<0a<sinx+cosxminimum value of sinx+cosx is -root2so a should be less than -root2Thanks & RegardsSunil RaikwaraskIITians Faculty
