Tan 120 is not defined ? .... i happen to come across and inquired about it?
tan 120= not defined, why?
Tan 120 is not defined because it is infinity. Additionally, tangent can be expressed as sin theta divided by cos theta. The sine of 120 is 1 while the cosine of 120 is 0. That would be 1 divided by 0, or division by zero; which is undefined.
What do you mean by that?
