Question

If the given angle is in standard position, find two positive coterminal angles and two negative coterminal angles. (Enter your answers as a comma-separated list.)
(a) 700°
positive angles
negative angles

(b)
5π/7
positive angles
negative angles

(c)
−π/3
positive angles
negative angles

Answer 1

Do you know what a coterminal angle is?

Answer 2

I was trying to start a discussion and help you, but you left....

Answer 3

Sorry! i'm here

Answer 4

Are you still here?

Answer 5

Sorry i was finding out how to use this site. This is my first time on it.

Answer 6

I have to go now tho.... (I am going to be back in an hour).
I'll post some instructions for you .

@Reaper534 maybe can help you. Sorry for bugging you, reaper..

Answer 7

for sure

Answer 8

now lets see

Answer 9

I dont think ive done this yet not sure how its solved

Answer 10

@AriPotta Do you know this?

Answer 11

I am back. (I was studying my Jewish stuff with a group...)

Now,
Coterminal angle:

For angle (lets say) 60, it will be
-300, -660, ... (subtracting 360 each time)
420, 780 ... (adding 360 each time)

Answer 12

hey i got it figured out! thank you so much though

Answer 13

The idea is, 30 and 390 is the same exact angle, see?

Answer 14

I apologize if i wasted your time.

Answer 15

That actually helps me understand it a bit better though. Thank you (:

Answer 16

I am sorry, I really had to go.... I should have given you the instructions or advices, but my connection snapped.
Just like many times when I try to put some fancy codes.

Answer 17

Its okay! you actually explained it very well, someone else helped me out dont worry. Can i fan you and if i have another question ill ask?

Answer 18

You can ask me without fanning me. Whenever I am online.
The thing is tho, that I am rarely online, due to my college.

Answer 19

Okay, if you're not busy right now i have another question..

Answer 20

Sure, go ahead.

Answer 21

okay, thank you so much, one second

Answer 22

Approximate, to the nearest 0.01 radian, all angles θ in the interval [0, 2π) that satisfy the equation. (Enter your answers as a comma-separated list.)
(a)
sin θ = −0.0134

θ =

(b)
cos θ = 0.9238

θ =

(c)
tan θ = 0.46

θ =

(d)
cot θ = −2.771

θ =

(e)
sec θ = −3.5

θ =

(f)
csc θ = 1.22

θ =

Answer 23

If it shows the question marks, try backing out and coming back into the conversation

Answer 24

you can refresh, and this is what I'll do.

Answer 25

I don't have a calculator with me, but lets say for the first problem.
Can you take the inverse sine?
sin^(-1) −0.0134 = find this, and then convert to radians.

Answer 26

Oh okay that makes sense.

Answer 27

but how do i take the inverse of the ones that arnt sin cos or tan

Answer 28

same thing?

Answer 29

well, I am sure there is something like inverse cot, sec and csc.
You CAN though, re-write them, using the rules below:

csc^-1 x = 1 / sin^-1 x
sec^-1 x = 1 / cos^-1 x
cot^-1 x = 1 / tan-1 x

It is the same thing for the inverses of sin cos and tan .

Answer 30

you can take an inverse secant (for instance) . (Nothing wrong with that)
