integral of+xe^{x^2}sin(x^2)

\int + x e^{x^{2}} sin (x^{2}) d x

\frac{1}{4} e^{x^{2}} sin (x^{2}) - \frac{1}{4} e^{x^{2}} cos (x^{2}) + C

Solution steps

\int x e^{x^{2}} sin (x^{2}) d x

Apply Integration By Parts

: \frac{1}{2} e^{x^{2}} sin (x^{2}) - \int e^{x^{2}} x cos (x^{2}) d x

= \frac{1}{2} e^{x^{2}} sin (x^{2}) - \int e^{x^{2}} x cos (x^{2}) d x

\int e^{x^{2}} x cos (x^{2}) d x = \frac{1}{4} (e^{x^{2}} sin (x^{2}) + e^{x^{2}} cos (x^{2}))

= \frac{1}{2} e^{x^{2}} sin (x^{2}) - \frac{1}{4} (e^{x^{2}} sin (x^{2}) + e^{x^{2}} cos (x^{2}))

Simplify

\frac{1}{2} e^{x^{2}} sin (x^{2}) - \frac{1}{4} (e^{x^{2}} sin (x^{2}) + e^{x^{2}} cos (x^{2})) : \frac{1}{4} e^{x^{2}} sin (x^{2}) - \frac{1}{4} e^{x^{2}} cos (x^{2})

= \frac{1}{4} e^{x^{2}} sin (x^{2}) - \frac{1}{4} e^{x^{2}} cos (x^{2})

Add a constant to the solution

= \frac{1}{4} e^{x^{2}} sin (x^{2}) - \frac{1}{4} e^{x^{2}} cos (x^{2}) + C

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

\int \frac{1 + x}{x} d x

\int \frac{1}{100 + t} d t

\int \frac{1}{9 y ^{2} + 64} d y

\int x e^{2 x} sin (x) d x
