Find the dr/d(theta) for:<br>r = (theta)sin(theta) + cos(theta)

maxonik [38]

$r=\theta\sin\theta+\cos\theta$

$\dfrac{\mathrm dr}{\mathrm d\theta}=\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}+\dfrac{\mathrm d(\cos\theta)}{\mathrm d\theta}$

By the product rule,

$\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}=\dfrac{\mathrm d(\theta)}{\mathrm d\theta}\sin\theta+\theta\dfrac{\mathrm d(\sin\theta)}{\mathrm d\theta}=\sin\theta+\theta\cos\theta$

and

$\dfrac{\mathrm d(\cos\theta)}{\mathrm d\theta}=-\sin\theta$

So we have

$\dfrac{\mathrm dr}{\mathrm d\theta}=\sin\theta+\theta\cos\theta-\sin\theta$

$\implies\dfrac{\mathrm dr}{\mathrm d\theta}=\theta\cos\theta$

Write the simplified expression: 2x + 3(x - 2) - 3(x -6)

Bas_tet [7]

Answer:

2x+12

Step-by-step explanation:

2x+3(x−2)−3(x−6)

Distribute:

=2x+(3)(x)+(3)(−2)+(−3)(x)+(−3)(−6)

=2x+3x+−6+−3x+18

Combine Like Terms:

=2x+3x+−6+−3x+18

=(2x+3x+−3x)+(−6+18)

=2x+12

Answer:

=2x+12
