    I need help with this integral.

    w= the integral from 0 to 5

    24e^-6t cos(2t) dt.

    i found the the integration in the integral table.

    (e^ax/a^2 + b^2) (a cos bx + b sin bx)

    im having trouble finishing the problem from here.

    Re: Integration

    What exactly are you having problems with? You have the anti-derivative, all you need to do now is evaluate it at then end points.
