Question

how do you get the answer 5π/6 by solving tan^-1(1/-√3) + 1π ? all the steps or any links that I can study them would be really great :)

Thanks

Answer 1

tan^-1(1/-√3)
first find the angle less than 90 dgrees ( in first quadran) that has a tan of 1/sqrt3

there's a standard triangle which can be used

Answer 2

thats anggle x which is 30 degrees or pi/6 radians

Answer 3

but we have negative 1 / sqrt3 which will givw an angle in the second quadrant
