Probably the equation is
In this case all solutions are
I've solved a trig problem and now I have tanx=pi/3, which i know is equal to .
Im struggling with putting this on a unit circle so I can solve for all of the possible angles. I would appreciate if someone could show me on a unit circle where the possible x's are for this and how i could find out the various angles (of which there are 4).
There are two special triangles you can use to find out the trigonometric ratios of the angles: 30, 45, and 60; the 45-45-90 triangle and the 30-60-90 triangle.
