Just someone who wants to know more about maths principally. Not a genius, yet aiming to be one.

comment Calculate the determinant of the matrix
Oh! So how could I explain it without an example?

comment Calculate the determinant of the matrix
Yes, I got 1 and -1 respectively. I don't see how's that different from what I found?

That doesn't answer my question in case it wasn't an indefinite integral.

I still have a question though, why is $3a^2b-b^3=0$ instead of $3a^2b-b^3=-1$?

comment Find the values of a,b,c such that a matrix has infinite, unique, and no solutions.
Oh, I thought you meant the fourth line in the matrix. If I ignore that one, the system has a unique solution.

Actually I am familiar with the formula. Never used it before, and I doubt this is what my professor was asking for, but this is a really good way to find it! Thank you!
