In a futile effort to get through Roger Penrose's Road to Reality, I’ve come upon complex number calculus and I have no back round in this topic. So what I am wondering is what do I need to understand before I can do complex number calculus and if there are any good textbooks on this topic.
Homework Statement
1. A 8 cm radius disk with a rotational inertia of .12 kg * M(squared) is free to rotate on a horizontal axis. A string is fastened to the surface of the disk and a 10 kg mass hangs from the other end. The mass is raised by using a crank to apply a 9 N * m torque to the...
i don't know if this will help but take the unit circle and reverse it. instead of looking for the angle then finding the value. look for the value then look for the angle that gives you the value. for arcsin(1), you would go along looking a the value of tan(angle) then when you find the...

1. I really don’t know how to do this with the integration methods I can remember right now and I don’t know how to get the greater than and less than numbers either.
2.Evaluate . This one I used L'Hopitals Rule once. Then I think I can use it one more time to...
A ball mass m falls from height h and collides elastically with a frictionless inclined plane; the plane is a 45 degree angle with the horizontal. The first spot it collides with is p1 and then it bounces and collides with the plane again at p2. I think the ball bounce off the inclined plane...
My AP physics C class has decided to get some sort of physics t-shirt and we are now trying to decide what to put on the t-shirt. So i was wondering if anyone here knows any good physics quotes. I'm mainly looking for quotes that are general or deal with Mechanics or E/M. thanks for any help...
Sorry I didn't know you wanted me show my efforts at the problem. well for the first one most of my work has been finding out what the value of the forces acting on the block are like the frictional force or the force of gravity parallel to the plane for both blocks. Unfortunately I don’t have...
The problem is I have two blocks on an inclined plane. They are connected by a metal rod. The bottom(2) mass provides the dominate force. Fiction is involved. They have different kinetic coefficients of friction. I need to know the acceleration of the system and the tension in the rod...
