Precalculus
David Cohen
Edition 3
Chapter 1, Section 1.1
Draw a number line. Then indicate the approximate location of the given number. Where necessary, make use of the approximations sqrt{2} is about 1.4, and sqrt{3} is about 1.7.
16. 1 - sqrt{2}
18. - sqrt{2} - 1
20. sqrt{2} - sqrt{3}
22. (2•sqrt{3} + 1)/2
@usn0814,
16. approximately -0.4
18. approximately -2.
20. approximately -0.3
22. approximately 2.2
In sequential order (I used the numbers of the questions), it would be 18, 16, 20, 22
@eigenvalue,
In sequential order, 16 comes before 18. It is probably a typo. I make tying errors all the time.
Tea time at Derry and Tom's.
@usn0814,
@usn0814, I was referencing the answers pertaining to the question number. It should be -2, -0.4, -0.3, 2.2.
