Plot the point (3, 2pi/3), given in polar coordinates, and find other polar coordinates (r, θ )of the point for which the following are true.

(a) r> 0, -2 pi < 0
(b) r < 0, 0 < 2 pi
(c) r > 0, 2 pi < 4 pi

(a)

(b)

(c)

Step-by-step explanation:

All polar coordinates of point (r, θ ) are

and

where, θ is in radian and n is an integer.

The given point is . So, all polar coordinates of point are

and

(a)

Substitute n=-1 in , to find the point for which .

Therefore, the required point is .

(b)

Substitute n=0 in , to find the point for which .

Therefore, the required point is .

(c)

Substitute n=1 in , to find the point for which .

Therefore, the required point is .

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
