integral of t^2*e^t

\int t^{2} \cdot e^{t} d t

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

Solution steps

\int t^{2} e^{t} d t

Apply Integration By Parts

: t^{2} e^{t} - \int 2 t e^{t} d t

= t^{2} e^{t} - \int 2 t e^{t} d t

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

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

Add a constant to the solution

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

\int \frac{1}{( u - 1 ) ^{3}} d u

\int 4 x^{2} - 2 x d x

\int (5 x^{3} + 4^{x} + 14 x^{7} - 2) d x

\int \frac{( x + 6 ) ^{6}}{2 x} d x

\int \frac{2}{x 4 x ^{2} - 1} d x
