Question

[]

Answer 1

first convert in to a form such that 0<theta<2pi

so we will add 2 pi to -10pi/3

what we will get??

Answer 2

make it first to a radian form... :)

Answer 3

it would be -5 pie over 3

look
\[-11\pi/3+2\pi=(-11\pi+6\pi)/3=-5\pi/3 \]

got it?

Answer 4

it depends if we have angle greater then 2pi or less than -2pi

we have just done simple addition

\[-11\pi/3+2\pi/1 = -11\pi/3 +6\pi/3 = -5\pi/3\]

we have taken LCM of denominator in order to do addtion

Answer 5

happy to help...! :)
