Hi everybody, I have this function to study ##\frac{(x+1)}{arctan(x+1)}## I need the limit to infinity,it's oblique and I have to find q,from y=mx+q. so q=lim(x->inf) ##\frac{(x+1)}{arctan(x+1)} -2x/\pi## I don't know how to solve it.the limit gives infinity to me.but calculators online give...

Thanks for reply, Point P is tangent, the question that teacher asked to me was "give me a qualitative consideration of velocity in ##\Omega##" For example the direction, and approximately the entity like "it's 1/3...2/3 of Va". The problem gives me just Va and nothing else. I tried to set...

< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > A rod rolls without creep. And the disk rolls without creep on Q. The rod can just moves on y. Which is the relation among Va and Vohm? Va= velocity in A My resolution: in Q we know that...

Hello everybody! I'm Lorenzo from Italy. I hope to find nice people here and a help ;) And I'd like to help ofc!
