Answer 1

okay so it says pi/3 or pi/6 how do i know which one?

Answer 2

Just multiply the angle, which was 60, by pi/180 \[\large 60 * \frac{ \pi }{ 180 }\]

Answer 3

danno i need the correct words, pwease use radians and degrees

Answer 4

60 degrees * pi radians /180 degrees

Answer 5

whats the difference between radians and degrees?

Answer 6

Degrees are more like percentages, which is why radians are more useful

But they're just different units. There's 360 degrees in a circle, and 2pi radians in a circle

Answer 7

what

Answer 8

example pls

Answer 9

That is an example... 2pi radians = 360 degrees

1 radian is equal to about 57 degrees.

Answer 11

pi/something=radian?

Answer 12

No, that's just the conversion factor. To convert degrees to radians, you multiply by pi radians/180 degrees

Answer 13

1 radian is equal to the length of the radius of a circle. Like this http://www.softmath.com/tutorials-3/cramer%E2%80%99s-rule/articles_imgs/2146/radian1.gif

Answer 14

why are all the radians pi over __ then?

Answer 15

Just to keep them exact. Those are only the exact ones. There's plenty of non-exact ones, like 0.15 radians or 5.4 radians etc

Answer 16

oki thanks

Answer 17

And cos most of the exact ones are fractions of 180. Like 60 degrees is 180/3

pi radians is equal to 180 degrees, so pi/3 radians is the same as 60 degrees
