Question $22$

Find the indefinite integral below.

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(4e^{4t}i-2sin(2t)j12cos(4t)k)dt$

Do not include an arbitrary constant vector.

$e^{4t}i-cos(2t)j3sin(4t)k$

$e^{4t}$i $cos(2t)j-3sin(4t)k$

$e^{4t}$i $cos(2t)j12sin(4t)k$

$e^{4f}$i $cos(2t)j3sin(4t)k$

$\{$:$\frac{e^{4t}}{4}$i $cos(2t)\}3sin(4t)k$
