(II) A 330-kg piano slides 3.6 m down a 28 incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-36). The effective coefficient of kinetic friction is 0.40. Calculate: (a) the force exerted by the man, (b) the work done by the man on the piano, (c) t

Single Variable Essential Calculus: Early Transcendentals 2
Use integration by parts, together with the techniques of this section, to evaluate the integral. \(\int x \tan ^{-1} x d x\)

Brief Applied Calculus
First make a substitution and then use integration by parts to evaluate the integral. \(\int t^{3} e^{-t^{2}} d t\)
