Use the process outlined in the lesson to approximate the number 2√5. use the approximation √5 ≈ 2.236 067 98.
find a sequence of five intervals that contain 2√5 whose endpoints get successively closer to 2√5. write your
intervals in the form < 2^√5 < 2^s for rational numbers and s.

answer: 3.26019516

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
