Let x=cost then t= cos^-1x and by putting x=cost we get sin^-1(2sint•cost)=sin-1(sint2t)=2t and t=cos^-1x so 2cos^-1x hence proved

Yes, it is an equivalence relation . Because For Reflexive a=b. So (a,a)€R And for symmetric (a,b)€R, a=b Then (b,a) €R For transitive (a,b)€R a=b -1 (b,c)€R b=c -2 From eq 1 and 2 a=c Then (a,c)€R So it is an equivalence relation

Determinant of skew symmetric matrix is always zero. For Example = Let's take a general skew symmetric matrix |0 b c| |-b 0 e| |-c - e. 0| 0(a+e²)-b(0-b)-(-ec)+c(be-0) =0-bec+cbe=0 Therefore determinant of skew symmetric matrix is always zero.
