Your Input

Find $$$\int e^{- t}\, dx$$$.

Solution

Apply the constant rule $$$\int c\, dx = c x$$$ with $$$c=e^{- t}$$$:

$${\color{red}{\int{e^{- t} d x}}} = {\color{red}{x e^{- t}}}$$

Therefore,

$$\int{e^{- t} d x} = x e^{- t}$$

Add the constant of integration:

$$\int{e^{- t} d x} = x e^{- t}+C$$

Answer

$$$\int e^{- t}\, dx = x e^{- t} + C$$$A
