hello all,
i am unaware of how to handle a delta function. from what i read online the integral will be 1 from one point to another since at zero the "function" is infinite. overall though i don't think i know the material well enough to trust my answer. and help on how to take the integral of a dirac delta function would be much appreciated. the kind of problems I am dealing with are similar to
[tex]\int[/tex]e^(-x^2) [tex]\delta[/tex](x+1)[1-cos(5 (pi/2) x)] dx from -infinity to 0
for this i solved the delta function for when x+1=0 since that is the only time when the function will have a value. i then subbed -1 for all x's and took the integral, assuming the delta function became 1.
thank you very much for help
