Question

I have a similar problem that I can't figure out. if theta = arctan(-1/squareroot 3)
what is theta in terms of pi?

Answer 1

if you multiply both sides by tangent

Answer 2

you can get rid of the arc tan which might be a little more easy on you

Answer 3

So theta=-30 degrees or -pi/6

Answer 4

you'd get Tan(theta)=-1/squarert(3)

Answer 5

which would match roadjester's picture

Answer 6

due to Opposite/Adjacent
