Question

.

Answer 1

what does that even mean?

Answer 2

It's the polar coordinate system. @Bgarza95

Answer 3

i dont even know what that is ill try another question

Answer 4

you have x = -3 , y = 2

so in order to find r you have to do : r = sqrt(2^2 + (-3)^2)
in order to find theta you have to do: theta = arctan(2/-3) you get - so you have to add 180 to it

Answer 5

oh ok

Answer 6

sqroot -3^2 + 2^2

Answer 7

sqroot 9+4

Answer 8

sqroot 13

Answer 9

arc tan 2/-3

Answer 10

-33.6?

Answer 11

-33.6 + 3.14

Answer 12

Okay im confused on this part..

Answer 13

no my friend not adding 3.14 .. adding 180 since you measure your angle from the begining (positive x axis)

Answer 14

(sqroot 13,146.6 radians ?

Answer 15

Maybe 146.6 degrees. 146.6 radians is a bit extreme.

Answer 16

yes its degrees

Answer 17

ok so the final answer is sqroot 13 and 146.6 degrees ?

Answer 18

be careful .. if your calculator are on degrees you get answers from it as degrees
when you click on the arctan you get in return degrees!!
unless you change it into radians it is degrees

Answer 19

yes.. seems right
