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

cos (a) - sin (a)

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= cos (a) - sin (a)

\frac{4}{ln ( x )}

x \to \frac{23}{2} lim (\frac{3}{2})

\int x^{2} ln (7 x) d x

\int \frac{4}{5} - \frac{7}{x} d x

e^{x} (x^{2} + 1)

What is the d/(da)(sin(a)+cos(a)) ?

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