FEYN CALC SYMBOL

TrickIntegrate


does an integration trick for the definite integral of ((1-t)^(a Epsilon-1) g[t]) from 0 to 1, yielding g[1]/a/Epsilon + Hold[Integrate][(1-t)^(a Epsilon-1) (g[t]-g[1]),{t,0,1}]. TrickIntegrate[t^(a Epsilon-1) g[t], t] gives + Hold[Integrate][t^(a Epsilon-1) (g[t]-g[0]),{t,0,1}], provided g[1] and g[0] exist.
