    The maximum value of sin \[x+cos\text{ }x\] is

    A)  1                                

    B)  \[-\,\,\sqrt{2}\]

    C)  \[\sqrt{2}\]       

    D)  \[-1\]

    Correct Answer: C

    Solution :

    The maximum value of \[a\sin \theta +b\cos \theta \] is \[\sqrt{{{a}^{2}}+{{b}^{2}}}.\] So, here a = 1, A = 1 Maximum value \[=\sqrt{1+1}=\sqrt{2}\]
