View attachment 8979A) Find all values on [0,2pie) such that (thita0) produces the tip of a petal (maximum magnitude of r) all values for which r=0, and sketch a graph?

a) r = 5 sin 2 (thita0)

a) r = 5 sin 3 (thita0)

a) r = 5 sin 4 (thita0)

B) considering what you can observe in the previous graphs, what are general guidelines for number, length and position of petals for a general rose curve: r = a sin b (thita0).

c) A polar curve in the frome r = d + a sin (thita0) is called a limacon and has several distinct variations, including a cardioid and a limacon with an inner loop. Create general guidelines for when these variations occur and explain what causes them to occur?
