tan(1) = 1.5574 where the angle is measured in radians.
If B is 90 degrees, Tan A is BC / AB. But I don't know what you mean by Tan A by 2.
That is not correct. "tan x" is a function that depends on the value of "x"; it is not always pi. tan(x) is pi only if 'x' is about 72.3 degrees, 252.3 degrees, or either of these added to a multiple of 360 degrees.
Tan 42 degrees = 0.9004

tan(135 degrees) = negative 1.
tan(-60 degrees) = - sqrt(3)
Well, darling, the value of tan(58.5 degrees) is approximately 1.612. So, if you're looking to impress someone with your trigonometry skills, go ahead and drop that little nugget of knowledge on them. Just don't expect them to be as impressed as they should be.
