$$[x]_S=\left[ \begin {array}{ccc} 1\\ -3\\ 0\end {array} \right].$$
Since we have $$x= (1,0,0)-3(0,1,0)+0(0,0,1),$$ then the coordinate matrix of $x$ in $R^3$ relative to the standard basis is $$[x]_S=\left[ \begin {array}{ccc} 1\\ -3\\ 0\end {array} \right].$$ | HuggingFaceTB/finemath | |
# Dynamic Mode Decomposition
The Dynamic Mode Decomposition (DMD) is a relatively recent mathematical innovation that, among other things, allows us to solve or approximate dynamical systems in terms of coherent structures that grow, decay, and/ or oscillate in time. We refer to the coherent structures as DMD modes. E... | HuggingFaceTB/finemath | |

# 198 is 369 Percent of what?
## 198 is 369 Percent of 53.66
%
198 is 369% of 53.66
Calculation steps:
198 ÷ ( 369 ÷ 100 ) = 53.66
### Calculate 198 is 369 Percent of what?
• F
Formula
198 ÷ ( 369 ÷ 100 )
• 1
Percent to decimal
369 ÷ 100 = 3.69
• 2
198 ÷ 3.69 = 53.66 So 198 is 369% of 53.66

$f \left(x\right) = {e}^{x} \sqrt{{x}^{2} - x}$ is increasing at $x = 3$
#### Explanation:
A function $f \left(x\right)$ is increasing at $x = a$ if $f ' \left(a\right) > 0$ and is decreasing at $x = a$ if $f ' \left(a\right) < 0$.
As $f \left(... | HuggingFaceTB/finemath | |
