Everytime I try to evaluate this integral, Mathematica 3.0 crashes and I get a message saying MathKernel caused an invalid page fault . I have tried this in Windows 95 and Windows NT environments but it always crashes everytime I try to evaluate the integrate[ ] I hope some one can help me try to resolve this problem Thanks swami swami at eng.umd.edu <<Calculus`DiracDelta` Constants T0=0 T1=870 T2= 910 T3= 925 T4= 1072 t1=2 t2=14 t3=17 Functions TMed[t_]:= (UnitStep[t]-UnitStep[t-t1])*(872.979+0.75444*t+7.7461*t^2-1.8634*t^3 )+ (UnitStep[t-t1]-UnitStep[t-t2])*( 867.8333+11.3515*t+0.0959916*t^2+0.00137935*t^3)+ (UnitStep[t-t2]-UnitStep[t-t3])*( 1411.55-100.136*t+7.66613*t^2-0.168752*t^3) lambdaSCM[T_] := 0.60762915519817362 - 0.00341076479341569083 T + 3.18080702232159939*10^-6 T^2 Integrate[lambdaSCM[TMed[t]],{t,0,z}]
