For this case we have the following expression:
tan 120º
Rewriting we have: tan 120º = sine 120º / cosine 120º
We can rewrite the expression based on an acute angle.
We have then:
tan 120º = sine 60º / - cosine 60º
Rewriting we have:
tan 120º = - tan 60º
Answer:
the function as 120º as a function of an acute angle is:
A. - tan 60º
