Many roller coasters today have loops, either as stand-alone loops or as parts of corkscrews. in stand-alone loops, the loops are teardrop shaped and not one complete circle. write a brief essay as to why you think they are constructed that way.

Determine the maximum r-value of the polar equation r =3+3 cos 0
