VC.40.SPH Determine the vector area increments perpendicular to each pair of basis vectors in Spherical Polar (SPH) coordinates. Note: When entering a Greek letter in the blanks below, you can either type the name of the letter (e.gt 'phi' for 0), or nd the letter in the Greek section of the calcpad. Be sure you are using lowercase Greek letters when needed! If you need to enter a plus or minus sign alone, enter it instead as 1 or -1, Remember the right hand rule. Remember that your tutorial has Hints in it, at the end of each chapter If you're stuck, they are often quite useful! The SPH coordinates are r, 9~ Ci. What are the three vector area increments perpendicular to each pair of basis vectors? d5\
