次の不定積分を求めよ。
(1) Ssin 4x cos
4x cos 2x dx
(2)
Scos 2x cos 3x dx (3) sin3xsinxdx
$14 (1) Ssin 4x0052 xdx
2
{ { sin bxc5 m 2 z} dx
= (1 + (-00162) + {- (00522)) + C
2
(2) Scos2x cos3xdx
- {5 (Osseos (-11) dx
= f (-5-5x-5^(-x))+c
=
1
to 54 5x - £5α (-2) fc
(1) (54325arde
=((cos 2x - 054x)de
-±(±542k- & safe) -C
= 5422-f5a4x+c
