00:01
So, as per question we are having this kind of situation.
00:03
So, let o x1, o x2 and o x3 be three axes in cartesian coordinate.
00:13
So, in cartesian coordinate system we have ds square is equal to the dx1 whole square plus dx2 whole square plus dx3 whole square.
00:27
So, now let the metric tensor be we are having this kind of matrix.
00:31
So, in first row of matrix we have g11, g12 and g13 and in second row we have g21, g22, g23 and in third row of matrix we have g31, g32 and g33.
00:53
So, as per this we have ds square is equal to the g at ij and it is multiplied by dx1 and dxj.
01:06
And let this is our first equation and this is our second equation.
01:11
So, when we compare both the equation we will get here g11 is equal to the g22 is equal to the g33 is equal to the 1 and value of gij is equal to the 0 which implies that i does not equal to the j...
