using the appearance of the interval s2 = c2t2-x2-y2-z2 under the Lorentz transformation demonstrates the contraction of length. in particular show that the length is contracted for an observer moving at a velocity v with respect to an object whose length is L0 in its remainder frame

Let F= (x2 + y + 2 + z2) i + (exp( x2 ) + y2) j + (3 + x) k . Let a > 0 and let S be part of the spherical surface x2 + y2 + z2 = 2az + 15a2 that is above the x-y plane and the disk formed in the x-y plane by the circular intersection between the sphere and the plane. Find the flux of F outward across S.

The plane x+y+z= 24 intersects the cone x2+y2= z2 in an ellipse. The goal of this exercise is to find the two points on this ellipse that are closest to and furthest away from the xy-plane. Thus, we want to optimize F(x,y,z)= z, subject to the two constraints G(x,y,z)= x+y+z= 24 and H(x,y,z)= x2+y2-z2= 0.

Let S be the surface with equation x2+y2-z2=1. (a) In a single xy-plane, sketch and label the trace curves z=k for k = -2,-1,0,1,2. In words describe what types of curves these are and how they change. (b) In a single yz-plane, sketch and label the trace curves x=k for k= -2,-1,0,1,2. In other words, describe what types of curves these are and how they change as k varies.
