Q/ find the area of triangle using vectors method

Determine the vector area increments perpendicular to each pair of basis vectors in Circular Cylindrical (CC) coordinates (dSpz, etc). Note: The CC coordinates are P. , .. What are the three vector area increments perpendicular to each pair of basis vectors? dS • When entering a Greek letter in the blanks below, you can either type the name of the letter (e.g. 'phi' for ), or find 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.
