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.

Hello class 12 inverse trigonometry chapter holds a good amount of weightage but in comparison to other chapters, it is easy to understand and questions can be made easily which again depends on the capability of a student. I would say if you can give a week including practice this chapter will be done
