Finding volume using triple integral

Click For Summary
To find the volume of the solid defined by the equations x^2+y^2 > 1, x^2+z^2 = 1, and x^2+y^2 = 1, a triple integral approach is necessary, using the integrand of 1. The integration should be set up in cylindrical coordinates, specifically using dz, r, and dθ. The suggested limits for z are from 0 to sqrt(1 - cos^2(θ)) and from 0 to sqrt(1 - sin^2(θ)). The volume calculation focuses on the first quadrant, with the final result being multiplied by 8 to account for symmetry. Reevaluating the coordinate system may provide a clearer path to the solution.

Homework Statement



I need to find the volume of a solid formed by the following equations:
x^2+y^2 > 1
x^2+z^2 = 1
x^2 + y^2 =1

The Attempt at a Solution



I know that it is a triple integral and the integrand is 1.
I also know that I need to use dzrdrd\theta.

I believe that you need two integrals, one with z going from 0 to sqrt (1-costheta^2) and the other with z going from 0 to sqrt (1-sintheta^2). I only want to find the volume in the first quadrant then I will multiply by 8.

Have you been told you need to use dz rd rd\theta ?

If so then rethink you co-ordinate system when integrating, and look at your functions and see if you can convert them into any other coordinate system you know of

What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
