The slope of the tangent line to
at
is given by the derivative of
at that point:

Factorize the numerator:

We have
approaching -1; in particular, this means
, so that

Then

and the tangent line's equation is

Answer:
I think it's called a term.
Hope this helps :)
sin(
)=Sin(
-0) =Sin 0=0
Option C Sin(
)=0
Also, using unit circle, Sin(
)=0
48 is the lowest denominator
