Here is what I have been trying: E.g. for any HeavisideTheta it puts an exclusion to where the argument is zero; for any Piecewise function it puts an exclusion inbetween the pieces. It won't perform additional analysis to figure out that the function is in fact continuous in your case, it just does what it would do for all Piecewise functions. Not very surprising IMO.Integrate can evaluate integrals of rational functions. It can also evaluate integrals that involve exponential, logarithmic, trigonometric, and inverse trigonometric functions, so long as the result comes out in terms of the same set of functions. Integrate can give results in terms of many special functions.$\begingroup$ Ok, so in general I can extract each region of a piecewise function, solve for the region (assuming the integration is possible), impose the continuity conditions as you did, and then stick each piece back together.
