Question

Determine two pairs of polar coordinates for the point (4, -4) with 0° ≤ θ < 360°.

Answer 1

do you hhave any idea..??

Answer 2

r and theta can be found at looking at the graph :)

Answer 3

where's the graph..?

Answer 4

M giving answer...just a moment..

Answer 5

ok

Answer 6

I got (6,pi/4) but im confused cuz

Answer 7

these are the answers
(4 square root of 2, 45°), (-4 square root of 2, 225°)

(4 square root of 2, 135°), (-4 square root of 2, 315°)

(4 square root of 2, 225°), (-4 square root of 2, 45°)

(4 square root of 2, 315°), (-4 square root of 2, 135°)

Answer 8

i converted it into polar

Answer 9

1) Let A be the point (x, y) = (4, - 4)
=> x = 4 and y = - 4
r = √(x² + y²) = √(16 + 16) = √32 = ± 4 √2
tan Θ = -4/4 = - 1
=> Θ = (i) 315º or - 45º ; (ii) 135º or - 225
Hence, the Polar Coordinates are (i) (4√2, 315º) (ii) (-4 √2, 135º)

Answer 10

hmm

Answer 11

i dont understand the polar coordinate part

Answer 12

how you get the digits 315 and 135

Answer 13

look the values of tan=-1 at 135 and 315 only..you have to take that values at which tan gives -1 in between 0 to 360 so these are two at which tan gives -1..

Answer 14

ahhh ok

Answer 15

you get it fully..?

Answer 16

is it possible to find polar coordinates from a polar coordinate?

Answer 17

for example (6,31^degrees)

Answer 18

wht means.??

Answer 19

how would i find the all it's polar coordinates from looking at (6,31^degrees)
