SUMMARY

The discussion centers on estimating the Lipschitz derivative for the first-order differential equation dy/dt = f(t,y) = -16t^3y^2, with the initial condition y(0) = 1. The exact solution is derived as y(t) = (4t^4 + 1)^-1. The partial derivative ∂f/∂y is calculated as -32yt^3. The main challenge presented is substituting the exact solution into ∂f/∂y to estimate the Lipschitz derivative.

Consider the first order differential equation
dy/dt = f(t,y)= -16t^3y^2, with the inital condition y(0)=1.
Estimate the lipschitz derivative for the differential equation by substituting the exact solution into ∂f/∂y.

=I found the exact solution by using the separable of variable and doing integration
which is y(t)= (4t^4 +1)^-1
And also i found the ∂f/∂y = -32yt^3
The question ask about by substituting the exact solution into ∂f/∂y to estimate the lipschitz derivative. I don't know how to substitute.
Does anyone knows about lipschitz derivative?

Help me Please.

Help me Please.

1) Read your textbook; or
2) Google 'lipschitz derivative'.
 
I can not find it. So, i was asking for help.
