Whats the final result of this equation: -z * d/dz(1/(1-a*z^(-1)))
$begingroup$
Okay so im really confused about this because in the book the solution is the equation and book solution
Now the book is using the quotient rule for this differentiation, Now I hate that rule so I thought why not try composition rule instead and the end result was different for me so I tried using online calculators and they gave the same solution I got which is The solution from an online calculator
Okay so now im just confuse which one is right and i dont know if this helps but the topic is z-transform for Digital Signal Processing course.
Thank you
