Answer:
1
Step-by-step explanation:
90°/n = 90°/∞ --> 0 , because when you divide number by huge number answer will become less and less, when you divide by ∞, answer will ---> 0.
cos(0°) = 1
1^(2n) = 1^(2∞)= 1^(∞) = 1, because 1 in any power = 1.
[tex]\lim_{n \to \infty} (1) = 1[/tex]
Because lim of constant is this constant.
