does this mean that it can stay at actively infected cells or it can move to a virus? meaning it doesn't have to go from actively infected cell to virus it can stay at actively infected?

well for pi E isn't doesn't appear in the system of equations 2, so is it because the infected cell produces the virus particles but stays intact, or maybe they are they negligible in the second system?

I was asked to compare the equations I have made to the equations given to find difference so I guess I was right? there should be some difference?

so is my equation for ##dE\over dt## correct for the figure? and what about the last equation ##dV\over dt## why is this different?

I have edited that in, could you help me?

Homework Statement In the following problem I am trying to extend the function $$f(x) = x $$ defined on the interval $$(0,\pi)$$ into the interval $$(-\pi,0)$$ as a even function. Then I need to find the Fourier series of this function.Homework EquationsThe Attempt at a Solution So I believe I...

okay so I understand what you are saying. Now I just need to calculate the following, $$a_n = 2 \int_0^1 (1-x)\cos (n\pi x) dx $$ then plug it into the formula below to get the form of the Fourier series, $$f(x) = \sum^\infty_{n=1} a_n \cos\frac{n\pi x}{L}$$ where L is 1

can I use the fact that it is a even function therefore B will be 0 and I will have to calculate A?

I am a little confused of the domain also. The only states that the function is f(x) = e^{-x} , x> 0 and f(-x) = f(x)

okay so below is the calculation of the integral but then how would I find the definite integral using -infinity and infinity? $$A(\alpha) = \frac{1}{\pi}\int f(u)\cos\alpha u du = \frac{1}{\pi} \int e^{-u}\cos \alpha u du = \frac{1}{\pi } \frac{e^{-x}(\alpha sin(\alpha x)- (cos(\alpha x...

I checked my answer on wolfram alpha and these calculations were correct. I actually did forget to include the $$\frac{1}{pi}$$ that was outside of the integral. Am I correct in using 0 to infinity to my bounds or should it be -infinity to infinity?
