If the trace of matrix `A=[[x-2,e^x,-sinx],[cos x^2, x^2-x+3,ln |x|],[0,tan^(-1)x, x-7]]` is zero, then x is equal to :

If the trace of the matrix A=[(x-2,e^(x), -sinx),("cos"x^(2),x^(2)-x+3,"In"|x|),(cot x,"tan"^(-1)x,x-7)] is zero, then x is equal to :

If the trace of the matrix A=[(x-2,e^(x), -sinx),("cos"x^(2),x^(2)-x+3,"In"|x|),(cot x,"tan"^(-1)x,x-7)] is zero, then x is equal to :

" If the trace of the matrix: "A=[[-1,0,2,5],[3,x^(2)-2,4,1],[-1,-2,x-3,1],[2,0,4,x^(2)-6]]" is "0" then "x" is equal to "

If the trace of the matrix A= [{:( x-1 ,0,2,5),( 3, x^(2) - 2 ,4,1),( -1,-2,x-3,1),(2,0,4,x^(2)-6) :}] is 0 then x is equal to

If the trace of the matrix A= [{:( x-1 ,0,2,5),( 3, x^(2) - 2 ,4,1),( -1,-2,x-3,1),(2,0,4,x^(2)-6) :}] is 0 then x is equal to

If the trace of the matrix A=({:(x-5,0,2,4),(3,x^(2)-10,6,1),(-2,3,x-7,1),(1,2,0,-2):}) assumes the value zero, then the value of x equals to

If sinx + cos x = sqrt7/2 where x in 1^(st) quadrant , then tan""(x)/2 is equal to

If 7cos^(2)x+sinx cos x-3=0 then x=
