Integral dari $$$e \sin{\left(x \right)}$$$

Temukan $$$\int e \sin{\left(x \right)}\, dx$$$.

Terapkan aturan pengali konstanta $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ dengan $$$c=e$$$ dan $$$f{\left(x \right)} = \sin{\left(x \right)}$$$:

$${\color{red}{\int{e \sin{\left(x \right)} d x}}} = {\color{red}{e \int{\sin{\left(x \right)} d x}}}$$

Integral dari sinus adalah $$$\int{\sin{\left(x \right)} d x} = - \cos{\left(x \right)}$$$:

$$e {\color{red}{\int{\sin{\left(x \right)} d x}}} = e {\color{red}{\left(- \cos{\left(x \right)}\right)}}$$

Oleh karena itu,

$$\int{e \sin{\left(x \right)} d x} = - e \cos{\left(x \right)}$$

Tambahkan konstanta integrasi:

$$\int{e \sin{\left(x \right)} d x} = - e \cos{\left(x \right)}+C$$

$$$\int e \sin{\left(x \right)}\, dx = - e \cos{\left(x \right)} + C$$$A
