Try online matrix calculators. There most certainly should be some.

comment Derivative of a weird Integral and Derivative of a Function
Hi Teckizt. You have to notice a pattern for the derivative part. First derivative is $1/(x-1)^2$. The third is $((3-2x)x^2)/(x-1)^2$. The four is $((4-3x)x^3)/(x-1)^2$. Notice the pattern?

comment Eigenvalues of a matrix $A$ such that $ A^2=0$.
@preeti It will be diagonalizable with entries from $R$ only if the $nxn$ matrix is symmetric with $n$ distinct eigenvalues.

Hi Nunoxic. I added Strang. I think that one complements well with engineering applications. EDIT: I also see that you chose it too!
