Re: Help - determinant

Hi Phia;

I presume you want the determinant of that matrix.

Can you take it from there?

Well I got that too but when I insert the value z I get different result because the solution must be 3i√2.

Hi;

What solution do you get because 3i√2 is not correct! Maybe you have the right answer and do not know it!
