I have either made progress or gone the wrong direction. Either way, here is the work that I have done since I made this question:
I first factored the , leaving <1,-2t,0> as the vector. Then, to multiply the two, I set as “u” and <1,-2t,0> as “v” to use the product rule. I found the derivative of “u” to be , which further simplifies to , which I multiplied against the scalar. I did the same with taking the derivative of the vector, and multiplying it by the .
At the end, I know have:
