ofcorse am right,, suppose i ask you sinx +siny + sinz =3, then ofcorse its possible when all are =1

i go with @shubhamsrg\[\sin ^{1}x+\sin ^{1} y+\sin ^{1}z \le \frac{ 3\pi }{ 2 }\]equality occurs when\[\sin ^{1}x=\sin ^{1} y=\sin ^{1}z = \frac{\pi }{ 2 }\]

you have \[\sin^{1}(x)+\sin^{1}(y)+\sin^{1}(z)=\frac{3\pi}{2}\] but the the very largest \(\sin^{1}(x)\) can be is \(\frac{\pi}{2}\) so they must each be \(\frac{\pi}{2}\), otherwise they cannot add to \(\frac{3\pi}{2}\)
