The goal of this problem is to sketch the curve associated with the following equation in polar coordinates = 3 sin 20 First, use a separate page to make a table of r and 0 values satisfying the equation (or else make a plot for the above equation using Cartesian coordinates) and use this information to sketch the graph of the curve in polar coordinates. (a) Use the linked page of curves and points, to identify the curve that you've sketched in the space below. Two-letter code for your curve: ? (b) Write the polar coordinates of the points P and Q shown on the linked page. Coordinates for P (7.0)=(-3,pi/4) Coordinates for Q (r, 0) (4, 5pi/4) Important: Because of nonuniqueness of polar representations, for each point, pick the coordinates (r, 0) satisfying the equation, where 0 ≥ 0 is the smallest possible (nonnegative) angle, in radians, which may be used to represent the point. Do not use decimals in your answers.

Transcribed Image Text:The goal of this problem is to sketch the curve associated with the following equation in polar coordinates = 3 sin 20
First, use a separate page to make a table of r and 0 values satisfying the equation (or else make a plot for the above equation using Cartesian
coordinates) and use this information to sketch the graph of the curve in polar coordinates.
(a) Use the linked page of curves and points, to identify the curve that you've sketched in the space below.
Two-letter code for your curve: ?
(b) Write the polar coordinates of the points P and Q shown on the linked page.
Coordinates for P
(7.0)=(-3,pi/4)
Coordinates for Q
(r, 0) (4, 5pi/4)
Important: Because of nonuniqueness of polar representations, for each point, pick the coordinates (r, 0) satisfying the equation, where 0 ≥ 0 is the
smallest possible (nonnegative) angle, in radians, which may be used to represent the point. Do not use decimals in your answers.
