a. Graph the curve r ( t ) = ( 4 + cos ( 18 t ) ) cos ( t ) i + ( 4 + cos ( 18 t ) sin ( t ) ) j + 0.3 sin ( 18 t ) k ; using two viewing angles of your choice to see the overall shape of the curve. b. Does the curve resemble a “slinky”? c. What changes to the equation should be made to increase the number of coils of the slinky?
