Wolfram Alpha Saved My Life

I am currently taking ECE 125. For the homework I was assigned, it consists of a lot of math. We are talking about digital filters. For the homework, we need to map the time domain transfer function into a difference equation into z transform. The concept itself is not hard, but when it comes to calculation, it is so easy to make an error. As the result, the digital filter we calculated is wrong.

I started to use Wolfram Alpha to double check my work, and that makes my life so much easier.

Once I entered a complicated math expression, Wolfram Alpha can simplify for me. I can use this as a check mark. If my digital filter is not working, at least I know I was doing fine in terms of simplifying the equation.
