Provide the differential expression d y = g ′ ( x ) d x dy=g^{\prime}\left(x\right)dx for the following function: g ( x ) = 3 − b cos ⁡ ( 2 x ) g\left(x\right)=3-b\cos\left(2x\right) , where b b is a constant

d y = 2 b sin ⁡ ( 2 x ) d x dy=2b\sin\left(2x\right)dx

d y = − 2 b sin ⁡ ( 2 x ) d x dy=-2b\sin\left(2x\right)dx

d y = b sin ⁡ ( 2 x ) d x dy=b\sin\left(2x\right)dx

d y = − b sin ⁡ ( 2 x ) d x dy=-b\sin\left(2x\right)dx

Problem 3

Provide the differential expression $d y = g^{'} (x) d x$ for the following function:
$g (x) = 3 - b \cos (2 x)$ , where $b$ is a constant

$d y = - 2 b \sin (2 x) d x$

$d y equals 2 b sine 2 x d x$

$d y equals b sine 2 x d x$

$d y = - b \sin (2 x) d x$
