Hi, I am very stuck on the following 2 problems. Help would be appreciated!

1) Let z and w be complex numbers satisfying |z| = 4 and |w| = 2. Then enter in the numbers |z+w|^2, |zw|^2, |z-w|^2, |z/w|^2 below, in the order listed above. If any of these cannot be uniquely determined from the information given, enter in a question mark.

2) Let z and w be complex numbers satisfying |z| = 5, |w| = 2, and z*(conjugate of w) = 6+8i. Then enter in the numbers |z+w|^2, |zw|^2, |z-w|^2, |z/w|^2 below, in the order listed above. If any of these cannot be uniquely determined from the information given, enter in a question mark.

Thanks in advance for the help,

Hello,

I am very stuck on the following question:

The spherical coordinates of (-3, 4, -12) are (x, y, z). Find tan(x) + tan(z).

If anyone understands, help would be appreciated!

Thanks in advance!
