Your Input
Find $$$\int \cosh{\left(1 \right)}\, dx$$$.
Solution
Apply the constant rule $$$\int c\, dx = c x$$$ with $$$c=\cosh{\left(1 \right)}$$$:
$${\color{red}{\int{\cosh{\left(1 \right)} d x}}} = {\color{red}{x \cosh{\left(1 \right)}}}$$
Therefore,
$$\int{\cosh{\left(1 \right)} d x} = x \cosh{\left(1 \right)}$$
Add the constant of integration:
$$\int{\cosh{\left(1 \right)} d x} = x \cosh{\left(1 \right)}+C$$
Answer
$$$\int \cosh{\left(1 \right)}\, dx = x \cosh{\left(1 \right)} + C$$$A
