Assume that (bn) is a bounded sequence such that lim sup bn = 10. You must prove the following statement in the two di erent ways, listed below. Here is the statement: 9 M 2 N; 8 n > M; bn > 8: (i) a direct proof, using the de nition of lim sup. (ii) a proof by contradiction. Question 1.8. De ne the sequence, (sn), via sn = n n + 1 cos(

it has the same slope and a different y-intercept

hope this : )

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

idk u tell me

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
