10.C. Two forms of function in polar coordinates are given by 1. r = f(0) and 2. F(r, 0) = 0 You can see that form 1 isolates the variable r on the left side whereas form 2 does not but has 0 on the right side instead. The graph below is of the polar equation r = 3cos0 - 2sin0. Write it in the form 1 and 2. C 5
