Answer:
Choice B and Choise C.
Step-by-step explanation:
Equivalent expressions are those expressions that have the same value but they look different.
Given the following expression provided in the exercise:

You need to remember the multiplication of signs in order to find the equivalent expressions:

Then:
- Eliminating the parentheses, you get this equivalent expression:

- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:

This is an equivalent expression to 
Answer:

Coefficients
Answer:
½ ln 3
Step-by-step explanation:
∫ sec²x / tan x dx
If u = tan x, then du = sec²x dx.
∫ du / u
ln|u| + C
ln|tan x| + C
Evaluate between π/4 and π/3.
ln|tan(π/3)| + C − (ln|tan(π/4)| + C)
ln|√3| + C − ln|1| − C
ln(√3)
½ ln 3
