If A is an n x n matrix function such that A and \(\frac{dA}{dt}\)are the same function, then A = c\(e^tI_n\)for some constant c.
True or false? why?
Please, help

Best ResponseYou've already chosen the best response.2\[\frac{dA}{dt}=A ~~but~~A\neq ce^tI_n\]therefore, it's false, right?

Best ResponseYou've already chosen the best response.2the area of ACDE = area ABE + area BCDE = AB *EB/2 + EB*BC = 4*4\(\frac{\sqrt{3}}{2}\)+4\(\sqrt{3}\)*11

Best ResponseYou've already chosen the best response.2since AB=4 , BC=11. got it? it is = 8\(\sqrt{3}\)+44\(\sqrt{3}\)=52\(\sqrt{3}\)

Best ResponseYou've already chosen the best response.1it need not be \(A=ce^tI_n\) merely \(A=e^tB\) for constant matrix \(B\)
