why did you take 2pie + the basic angle ? And how did you convert your values into pie ? Thank you so much btw! i really appreciate the help <3
If you work in degrees, the conversion ratio is:
180⁰ = pi radians.
So for tangent positive,
The two initial angles within the range for 0⁰ to 360⁰ is alpha, 180⁰ + alpha.
For the 3rd angle, use alpha + 360⁰ (or alpha + 2pi)
Note that the domain to find angles needs to be changed as I have written. Thus, the basic angle is outside the domain
