Which of the following pairs of coordinates represents the same point in polar coordinates? Check all that apply.

A. (r, theta) and (-r, theta)

B. (r, theta) and (-r, theta+2pi)

C. (r, theta) and (-r, theta+pi)

D. (r, theta) and (r, theta+2pi)

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
