SUMMARY

The discussion focuses on solving the differential equation y = C(e^(-αt) - e^(-βt)), where C, α, and β are constants with C > 0 and 0 < α < β. Participants emphasize the importance of differentiating the equation to find dy/dt and setting it to zero to solve for t. The solution reveals that t = 1/(β - α) * ln(β/α) is the critical point where the derivative equals zero. This method effectively demonstrates how to analyze the behavior of the function over time.

Homework Statement


X--Y----Z, starting with X only


Homework Equations


y=C(e^-(alpha*t) -e-^beta*t)

C, alpha, beta constts SUCH THAT C >0 0<alpha <beta

show dy/dt= 0 imply t = 1/ (beta -alpha )*ln (beta/alpha)


The Attempt at a Solution



no idea!

Well, since it asks you to show that dy/dx= 0, have you differentiated
[tex]y= c(e^{-\alpha t}- e^{\beta t}[/tex]?

Set that derivative equal to 0 and solve for t.
 
Thanx, I trying to differentiate. Bt now sorted out! cheers!
