Question Number 168881 by Eulerian last updated on 20/Apr/22
 sin(π(√(ix))) + sinh(π(√(ix))) = 0      Find all the real value/s of x.
$$\:\mathrm{sin}\left(\pi\sqrt{\mathrm{ix}}\right)\:+\:\mathrm{sinh}\left(\pi\sqrt{\mathrm{ix}}\right)\:=\:\mathrm{0} \\ $$$$\: \\ $$$$\:\mathrm{Find}\:\mathrm{all}\:\mathrm{the}\:\mathrm{real}\:\mathrm{value}/\mathrm{s}\:\mathrm{of}\:\mathrm{x}. \\ $$

sin t +sinh t =0 ⇒ t=0  π(√(ix))=0 ⇒ x=0
$$\mathrm{sin}\:{t}\:+\mathrm{sinh}\:{t}\:=\mathrm{0}\:\Rightarrow\:{t}=\mathrm{0} \\ $$$$\pi\sqrt{\mathrm{i}{x}}=\mathrm{0}\:\Rightarrow\:{x}=\mathrm{0} \\ $$
