Below are sample questions representative of the exercises included on this worksheet and related TRIG.131 Recognize and graph common polar curves Student Copy skill assessments:

Problem 1Difficulty: Mastery
Classify these equations in order: r = 5, theta = pi/3, r = 2 sin(4theta), r = theta/3.
Acircle, line, rose, spiral
Bline, circle, spiral, rose
Crose, spiral, circle, line
Dspiral, rose, line, circle
Solution & Explanation:A constant r is a circle, a constant theta is a line, sine with 4theta is a rose, and r proportional to theta is a spiral.
Problem 2Difficulty: Mastery
Which comparison of r = 6 cos(theta) and r = 6 sin(theta) is correct?
ABoth are lines through the pole with slope 6
BBoth are six-petal roses
CBoth are spirals with the same growth rate
DBoth are circles of radius 3 passing through the pole; their centers are on the positive x-axis and positive y-axis respectively
Solution & Explanation:Each has radius abs(6)/2 = 3. The cosine form centers on the x-axis, while the sine form centers on the y-axis.
Problem 3Difficulty: Mastery
Which feature fits r = 4 cos(theta) - 4 sin(theta)?
Aline 4x - 4y = 0
Bfour-petal rose with diagonal petals
Ccircle centered at (2, -2) with radius sqrt(8)
Dspiral shifted downward
Solution & Explanation:Multiplying by r gives x2 + y2 = 4x - 4y, so the circle has center (2, -2) and radius sqrt(8).
