(b) Your graph should pass through the origin. At what value(s) of 8 does your graph
pass through the origin?
(c) Explain, in a few sentences, what causes a graph of a function in polar coordinates
to pass through the origin. How is this different from what makes a graph of a
function in rectangular coordinates pass through the origin?
7. Using another polar coordinate grid, graph the function r(0) = 4 + 2sine. What
difference(s) do you notice between this graph and the one in the previous problem?
How could we anticipate these differences just by looking at the formula for each
function?
