Unformatted text preview: ( r 1 , sin θ ) 7 → ( A, sin θ ) is singular when θ = 0 . 3. The jacobian is singular for all values of ( θ , φ , α ) . The triangle with sides of length R and r and hypotenuse given by line segment from origin to particle is a right-angled triangle. The particle moves on the surface of a sphere. 4. When we rotate about the axis by 2 π / 3 the vector e 1 becomes ˜ e 1 = e 2 . 1...
