I am recently trying to identify system parameters with projection algorithm, but faced a problem, and the dynamic model is the following:
\ddot{y}(t)+a\cdot\dot{y}(t)=b\cdot e(t)
The true value of a is 2.8, b is 0.1.
While inputing volt e(t)=12sin(2\pi t)+5sin(2t), I can get a good...
Well, do you mean that:
Schwarz inequality
= Cauchy–Schwarz inequality
= \left\|[x,y]\right\|\leq\left\|x\right\|\left\|y\right\|?
I think so either, thus I want to figure it out.
Both of your answers are helpful, thanks. :smile:
Sorry about used wrong symbol, and I have modified.
I know triangle inequality.
But the question still is "are Schwarz inequality and Cauchy–Schwarz inequality same?"
Thanks for your reply. :smile:
I found many information showed Schwarz inequality and Cauchy–Schwarz inequality are same on books and internet, but my teacher's material shows that:
Schwarz inequality:
\left\|[x,y]\right\|\leq\left\|x\right\|+\left\|y\right\|
Cauchy–Schwarz inequality...
