1. The problem statement, all variables and given/known data I have the transfer function: F(s) = s^3 / ((s+12)(s+550)(s+680)) Find the lower cutoff frequency (3dB point) 2. Relevant equations s = jw 3. The attempt at a solution I set the equation equal to 1/sqrt(2), use s = jw, and try to solve for the frequency. Now I'm just supposed to "Put it into your calculator and off I go", but what exactly do I put into my calculator? I have a Ti-84, is that able to solve these types of problems? What's throwing me off is the imaginary term 'j', I'm not exactly sure what to do with it when solving this polynomial.
