I want to find ##\|G\|_\infty##, the solution in the pic uses the Bode plot. But to tell you the truth I am worse at drawing it.
So basically what I thought is I want to find: ##|G(i\omega)|=1/\sqrt{(25−\omega^2)^2+9\omega^2}##.
So basically I much prefer to find the minimum value of what is in the sqrt from highschool calculus methods (differentiating and equating to zero).
I found something of the sort of 24.21 in the denominator, which is close to 25 but far from 15.
Am I correct in my reasoning?
