integral of-e^{-x}2x

\int - e^{- x} 2 x d x

- 2 (- e^{- x} x - e^{- x}) + C

Solution steps

\int - e^{- x} \cdot 2 x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 2 \cdot \int e^{- x} x d x

Apply Integration By Parts

= - 2 (- e^{- x} x - \int - e^{- x} d x)

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

= - 2 (- e^{- x} x - e^{- x})

Add a constant to the solution

= - 2 (- e^{- x} x - e^{- x}) + C

d er i v a t i v e y = 2 t (3 t^{2} - 5)^{3}

\frac{d}{d x} (e^{x} (x^{2} + 5 x))

\frac{d}{d x} (x 3 x - 2)

x y^{^{'}} + y = 0, y (4) = 6

d er i v a t i v e f (x) = \frac{4}{x} - \frac{2}{x ^{3}} + \frac{1}{x ^{4}}
