Homework Help Overview

The discussion revolves around verifying the derivative of a vector function. The original poster expresses uncertainty about their calculation due to a lack of access to computational tools.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are examining the validity of the derivative and questioning the domain of the vector function. There are attempts to clarify the conditions under which the derivative holds true.

Discussion Status

Participants are actively engaging in the discussion, with some providing insights on the domain and specific components of the vector. There is no clear consensus yet, but the conversation is focused on exploring the implications of the derivative and its components.

Contextual Notes

There are indications of constraints regarding the values of t, with suggestions that certain conditions may limit the validity of the derivative. The original poster's access to tools for verification is also noted as a limitation.

Check that domain section...
 
ahh should be r >0 right? is the derivative right too? thanks!
 
No. Look what happens to the i vector when you have t=3
 
oh f word...
can i say, t < 0?
 
Well, the thing is that it can go above 0... but how far?

Start looking at the equations and ask yourself where each one has a valid result. For example, the i component can be t=<2
