2. ### Show a derivative satisfies an equation

Would someone mind checking this for me? Show that $y=x|x|$ satisfies the equation $\frac{dy}{dx}=2\sqrt{|y|}$ If $x>0$, then $y=x^2$ Hence $\frac{dy}{dx}=2x=2\sqrt{|x^2|}=2x$ If $x<0$, then $y=-x^2$ Hence $\frac{dy}{dx}=-2x$ as $x<0$, $-2<0$ we have a negative times a negative which is...
3. ### Finding the solution to differential equations that satisfies the initial condition.

dP/dt=8sqrt{pt}, P(1)=6 This is my working and i prove that it does satisfy the initial condition but apparently i am still incorrect: dP/sqrt{p}=8sqrt{t}dt Integrating both sides we get: 2sqrt{p}= (16t^3/2)/3 + C Using P(1)=6: 2sqrt{6}= (16(1)^3/2)/3 + C C= 2sqrt{6} -16/3 Substituting...
4. ### Find a nonhyperbolic matrix which satisfies certain conditions

For $e^{At} = 1/2\begin{bmatrix}e^{2t}+e^{-t} & e^{2t} - e^{-t} \\ e^{2t}-e^{-t} & e^{2t}+e^{-t}\end{bmatrix}$ for all t $\in$ $\mathbb{R}$. how to find A?
5. ### Find a nonhyperbolic matrix which satisfies certain conditions

A nonhyperbolic matrix A for which the planar system $\overrightarrow x' = A \overrightarrow x$ has an equilibrium point at (0,0) with the x-axis as a stable curve and the y-axis as an unstable curve. Does this matrix exist? if so, could you show me that matrix?
6. ### look for the value that satisfies the equation

please explain how can I answer this one :) I know the answer should be a.) -4 & b.) -1. could you explain how will I come up with that answer? Thank you :)
7. ### Is there a composite number that satisfies these conditions?

we know that if $q=4k+3$ ($q$ is a prime), then $(a+bI)^q=a^q+b^q(I)^{4k+3} =a -bI(mod q)$ for every gaussian integer $(a+bi)$ ,Now consider a composite $N=4k+3$ satisfies this condistion for $a+bi=3+2i$, I use Mathematica8 and find no solutison$less than$5\cdots 10^7\$, can someone find a...

[SOLVED]Trying to find a sequence that satisfies specific characteristics Hi everyone! I heard this is a great place to get/give help with math questions/explanations. I was wondering if someone could help me out. I'm trying to find a sequence xn that satisfies ' Ʃ|xn|2 < infinity ' and...
11. ### What is an example of a model that satisfies ZFC?

From what I know, a model is a set of things that "give" an "interpretation" of the axioms such that the axioms are true of the "things" in the set. Is this right? I know there are many, many examples of such "sets of things," models, interpretations, structures, etc. of ZFC, but I don't have...

13. ### Showing that the dual space of bilinear maps V x W -> R satisfies tensor property

Let U,V and W be finite dimensional vector spaces, and define B to be the vector space of all bilinear maps V \times W \to \mathbb{R}. Given a bilinear map \alpha : V \times W \rightarrow U, define \tilde{\alpha}: B^* \rightarrow U^{**} by \alpha(\psi)(\sigma) = \psi (\sigma \circ \alpha)...
14. ### How to show that a function satisfies a differential equation?

Hi I'm doing a biology based maths course and this is driving me crazy, I just don't quite know how to show that this function satisfies the differential equation? Obviously I'm not expecting you guys to do this for me, but if you could just point me in the right direction, I don't know if I...
