    tan2(x) = 1 / √3

    I have to solve for x from -360 to 360.
    I only have 15,-165,195,-345 so far. The rest are suppose to be -255, 105 and 285 but I have no clue how to get them. I have to show my work btw.

    there is tan 2x graph here
    tan 2x can be imagined as two tan x squashed into -360 to +360
    u want + values so 8 values total
    add 15 to each of intersection at x axis

    -345
    -255
    -165
    -75
    +15
    +105
    +195
    +285
