New issue 2489 by [email protected]: Integral of two delta functions evaluates incorrectly
http://code.google.com/p/sympy/issues/detail?id=2489
x, x_1, x_2 = symbols('x,x_1,x_2') f = x_2 * DiracDelta(x-x_2) * DiracDelta(x_2-x_1) integrate(f, (x_2, -oo, oo))
x_1 The expected result is x_1*DiracDelta(x-x_1) -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
