Your Input
Find $$$\int 2 \sin{\left(2 \right)}\, dx$$$.
The trigonometric functions expect the argument in radians. To enter the argument in degrees, multiply it by pi/180, e.g. write 45° as 45*pi/180, or use the appropriate function adding 'd', e.g. write sin(45°) as sind(45).
Solution
Apply the constant rule $$$\int c\, dx = c x$$$ with $$$c=2 \sin{\left(2 \right)}$$$:
$${\color{red}{\int{2 \sin{\left(2 \right)} d x}}} = {\color{red}{\left(2 x \sin{\left(2 \right)}\right)}}$$
Therefore,
$$\int{2 \sin{\left(2 \right)} d x} = 2 x \sin{\left(2 \right)}$$
Add the constant of integration:
$$\int{2 \sin{\left(2 \right)} d x} = 2 x \sin{\left(2 \right)}+C$$
Answer
$$$\int 2 \sin{\left(2 \right)}\, dx = 2 x \sin{\left(2 \right)} + C$$$A
