Gunakan integral subtitusi : Jadi,

Gunakan integral subtitusi :

$u equals sin invisible function application x fraction numerator d u over denominator d x end fraction equals cos invisible function application x d x equals fraction numerator d u over denominator cos invisible function application x end fraction$

Jadi,

$integral cos invisible function application x. cos invisible function application open parentheses sin invisible function application x close parentheses d x integral cos invisible function application x. cos invisible function application open parentheses u close parentheses fraction numerator d u over denominator cos invisible function application x end fraction equals integral cos invisible function application u d u equals sin invisible function application u plus C equals sin invisible function application open parentheses sin invisible function application x close parentheses plus C$
