Question

Can someone help me with finding coterminal angles

Answer 1

sure thing

Answer 2

the question?

Answer 3

Ok: find a coterminal angle between 0 degrees and 360 degrees with the given number 11pi/3

Answer 4

Try subtracting or adding by 2 pi, the amount of radians in a full revolution, leaving you exactly where you started, a coterminal angle.

Answer 5

would i need to transform 11pi/3 into a mixed number?

Answer 6

if i wanted to subtract 2pi from it?

Answer 7

no, give it a common denominator and add. because you want your answer to be in radians still

Answer 8

so it would be 17pi/3

Answer 9

correct?

Answer 10

can you explain that again, the part with the common denominator?

Answer 11

Paste that in google u will get the answer

Answer 12

i would need a common denominator for 11pi/3 and 2pi

Answer 13

well, you have 11pi/3 and you want the coterminal angle on the unit circle. so you would add 2pi

Answer 14

a common denominator is needed to do so

Answer 15

so you would do this

Answer 16

\[2\pi/1 = 6\pi/3\]

Answer 17

that way you can add 11pi/3 and 6pi/3.

Answer 18

and 6pi/3 shares a common denominator with 11pi/3

Answer 19

am i right?

Answer 20

ok

Answer 21

that makes sense

Answer 22

yep. :)

Answer 23

ok thanks for helping

Answer 24

lol

Answer 25

if i had to find a positive and negative coterminal angle for 5pi/4

Answer 26

-3pi/4 and 13pi/4
