The homework worksheet is attached to the previous post. Do second page.
Today in class our only new content was to learn about angles described as bearings. For navigation and surveying, all bearing are angles east or west from a north/south line. So
S 35 E means rotating 35 degrees east of a southward line.
We read in our textbook about Trigonometry and Bearings. Understand the difference between bearings for flights vs bearings for navigation or surveying.
We went over HW #4 (problems 1-15 from worksheet). Questions. We did another problem like #14 – find the area of the triangle. Also modeled: finding the side of a regular pentagon inscribed in a circle if you know the radius.
Do problem 21 together (the sketch with the swamp).
Modeling and trying: #38 from textbook for flight angles.
Work on the rest of the worksheet as HW #5.
Assign webassign over the same thing, to be completed by Tuesday at 11:59 pm.
Quiz next time over 4.8 – a lot like worksheet. Do not worry about the two hard problems.
TEST NEXT MONDAY OVER 4.7-8.
We got to view our 4.7 quizzes. Will be returned next time.
Remember that you need to do your webassign!!!
Some hints on the webassign:
Remember that air navigation bearing are in clockwise degree rotation from due north.
On the water slide problem: On the question about describing the angle in terms of d, you are writing an inverse expression with a d in it.
When it asks for interval notation: [lower limit, upper limit]
Yes, you really are doing a lot of calculations with your calculator that are either trig functions or inverses. (I counted 16.) Be sure you are set on degrees, not radians. CAREFUL WITH ROUNDING... follow instructions. I will drop 1 wrong question from your score.
