Answer:the awnser is A i beleive not 100% sure
Setting
(1)×3 and (2)×5
Subtract both
explain further on this pls?
a = π n for n element Z
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
