Question

so so very lost with this.
Find the reference angle for the given angle.
(a) 10π/3
(b) 33π/4
(c) −35π/6

I would like to understand how to do one of them at least.

Answer 1

just subtract multiples of 2pi so that 0<the resultant < 2pi

Answer 2

or add, if original is negative

Answer 3

so for A) i got \[-4\pi/3\]

Answer 4

but that was the wrong answer

Answer 5

i did that for A, B, and C. but i got the wrong answers

Answer 6

is \[ 0<\frac {-4 \pi}{3}< 2\pi\]
