Statement I The system of linear equations `x+(sin alpha )y+(cos alpha )z=0` `x+(cos alpha ) y+(sin alpha )z=0` `-x+(sin alpha )y-(cos alpha )z=0` has a not trivial solution for only one value of ` alpha ` lying between ` 0 and pi`. Statement II `|{:(sin x, cos x , cos x),( cos x , sin x , cos x) , (cos x , cos x , sin x ):}|=0` has no solution in the interval `-pi//4 lt x lt pi//4 ` .A.
