How to write a script

  • Example 1 : Differentiate

    x = Symbol('x')
    diff(cos(x)*x,x)

  • Example 2 : Integrate

    x = Symbol('x')
    integrate(cos(x)*x,x)

  • Example 3 : Expand

    x = Symbol('x')
    y = Symbol('y')
    expand((x+y)**3)

  • Example 4 : Simplify

    x = Symbol('x')
    simplify((x**2-1)*(x**2+1))
