Step 1
In order to compute the derivative of the vector-valued function:
Differentiate the vector function on a component-by-component basis using the chain rule
Step 2
We differentiate the vector function on a component-by-component basis using the chain rule. This yields:
(sin2t)=cos2t(2t)=2cos2t
(et2)=et2(t2)=2tet2.
So the derivative is given by
r(t)=2cos2t,2tet2.
Step 3
Hence, the final answer is:
r(t)=2cos2t,2tet2.
