Thank you very much!

No, this is the quickest method. \(\quad\quad \quad\)

Since the maximum real value for \(\sin \theta\) and \(\cos \theta\) is \(1\), LHS cannot be larger than \(\sqrt{3}+1 < 4\), therefore, there is no real root.

Your method is right, but the maximum value of LHS is not \(\sqrt3+1\).

I did not say that the maximum value is \(\sqrt{3}+1\). What I meant was LHS \(\ne\) RHS.

Thanks! I also used the same method to solve the question in exam and wondering if it was correct or not.
