- Write the equations for converting from cylindrical torectangular coordinates. In what situation would you usecylindrical coordinates?(b) Write the equations for converting from spherical torectangular coordinates. In what situation would you usespherical coordinates?Situation: A client has just inherited a property. The deed is quite old, but she knows where the front two corners of the property are and that the distance between them is 210 feet. The shape is an irregular quadrilateral and the other three sides have distances of 515 feet, 232 feet, and 542 feet in a clockwise direction from the front left corner. More importantly, it is known that the front left corner of the property is a right angle.A bridge is built in the shape of a parabolic arch.
