Question Sequence

Question 1.1

Recall how to componentwise integrate a vector-valued function

r(t) = <x(t), y(t), z(t)> = x(t)i + y(t)j + z(t)k.

Identify the components of the integrand r(s) = $asi + 6s2j + $bk.

x(s) = nc1ItEz0kR4=s

y(s) = yBhAQ+3VvjM=s2

z(s) = iSba6t70dtA=

Correct.
Incorrect.
