SymPy Gamma

SymPy:

integrate (x*sin (3*x),x)

$\int x \sin{\left(3 x \right)}\, dx$

integrate(x*sin(3*x), x)

Plot:

plot(-x*cos(3*x)/3 + sin(3*x)/9)

Roots:

solve(-x*cos(3*x)/3 + sin(3*x)/9, x)

$x =$

diff(-x*cos(3*x)/3 + sin(3*x)/9, x)

$\frac{d}{d x} \left(- \frac{x \cos{\left(3 x \right)}}{3} + \frac{\sin{\left(3 x \right)}}{9}\right) =$

series(-x*cos(3*x)/3 + sin(3*x)/9, x, 0, 10)
