use unitary method
\[\Pi=180 degree\]

remember
\(\pi ^r = 180 ^o\)
so,
\(x^o = \pi/180 \) radians
and
\(x^r = 180/ \pi\)degrees.

to convert degrees into radion multiply the degree with \[\Large \frac{\pi}{180}\]
to convert radion into degrees multiply he radians with \[\Large \frac{180}{\pi}\]

sorry, mistyped it
\(x^o = x \times \pi/180\)
and
\(x^r= x \times 180/\pi \)

Sure o: This one problem I'm doing now is converting 11pi/12 to degrees.

so what you'll multiply that with ?
11pi/2 * .... ?

180/pi or pi/180 ??

180/pi.. I think you switched them back up there o:

no, i didn't switch
and 180/pi is correct, so what you got as degree angle ?

you wrote to get radians, you use 180/pi. o: and 165.

sorry, my bad.
\(x^o \times \pi/180=x^r \\x^r \times 180/\pi=x^o\)
and 11pi/2 * 180/pi = 11 *180 /2 = 11*90 = 990
how u got 165 ?
