Let's call trade balance b, exports e and imports i.
We now construct formula.
Put in the data from last year.
U.S trade balance for that year is -690 billion dollars.

Remember, a reference angle is a positive acute angle that represents an angle θ of any measurement.
a)
, then its reference angle is
b)
is in the second cuadrant, then its reference angle is
c)
, then it is in the first cuadrant and the reference angle is
.
d)
and it is in the third cuadrant, then its reference angle is
For f(-2), x will equal -2.
Plug the x-value into the equation:
A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):
Solve the problem:
f(-2) will equal 1/2.
