Question

sketch the polar equation

r = 4sin(t)

Answer 1

Start with your critical points. 0, pi/2, pi, 3pi/2, 2pi
you should be familiar with the values of sin(t) at these points. multiply by 4 and plot the points, connect the point to obtain a rough sketch

Answer 2

don't i have to find the rectangular equation for this first?

Answer 3

you can plot it in rectangular coordinates...but since the radius is given in terms of an angle, you can plot it directly to a polar plot

Answer 5

True, can you help me graph it using rectangular coordinates? Haven't gotten around using polor coordinates yet
