\frac{d}{d a} (sin (2 a) + sin (a))

cos (2 a) \cdot 2 + cos (a)

Solution steps

\frac{d}{d a} (sin (2 a) + sin (a))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d a} (sin (2 a)) + \frac{d}{d a} (sin (a))

\frac{d}{d a} (sin (2 a)) = cos (2 a) \cdot 2

\frac{d}{d a} (sin (a)) = cos (a)

= cos (2 a) \cdot 2 + cos (a)

What is the d/(da)(sin(2a)+sin(a)) ?
The d/(da)(sin(2a)+sin(a)) is cos(2a)*2+cos(a)
What is the first d/(da)(sin(2a)+sin(a)) ?
The first d/(da)(sin(2a)+sin(a)) is cos(2a)*2+cos(a)
