1. The problem statement, all variables and given/known data Transform the vector A = x2 - y5 + z3 into spherical coordinates at (x= -2, y= 3, z=1 ). 2. Relevant equations http://www.equationsheet.com/eqninfo/Equation-0348.html http://en.wikipedia.org/wiki/Spherical_coordinate_system 3. The attempt at a solution I know the transformation matrix and the transformation formulas from Cartesian to Spherical, but how do I incorporate the given point (-2,3,1) ? Thank you.
