Explain spherical coordinates. First tell me the names of the three variables. Next, provide a real-world example where they could be useful, and tell me what the variables are measuring in your example. Then, provide formulas relating spherical coordinates to Cartesian coordinates. Explain cylindrical coordinates. First tell me the names of the three variables. Next, provide a real-world example where they could be useful, and tell me what the variables are measuring in your example. Then, provide formulas relating cylindrical coordinates to Cartesian coordinates. 1uizlet
