Solution To use the integration by parts formula, we need to split “ xe x dx ” into two parts: the “ u ” part and the “ dv ” part. Notice that the “ dv ” must include dx ”. In this example, we let u = x , dv = e x dx . Then we need to compute “ du ” and “ v ”: du = dx , v = Z e x dx = e x . According to the integration by parts formula, we have Z xe x dx = xe x - Z e x dx . Z
