Evaluate \(\int\)(cos4x + sin3x)dx

A.

sin4x - cos3x + k

B.

sin4x + cos3x + k

C.

\(\frac{1}{4}\)sin4x - \(\frac{1}{3}\)cos3x + k

D.

\(\frac{1}{4}\)sin4x + \(\frac{1}{3}\)cos3x + k

Correct answer is C

\(\int (\cos 4x + \sin 3x) \mathrm d x\)

= \(\frac{1}{4} \sin 4x - \frac{1}{3} \cos 3x + k\)
