Help with inverse funtions (Algebra II)

Hey everybody, if you're struggling with with these inverse functions, here's a good video of some dude explaining them a little bit. Feel free to email me if you have any questions or need extra help. (mrfritz23@gmail.com)

Wednesday

Hello all! Today's a great day for outdoor homework! Studies show people think better when they breathe fresh air and are in the sunlight.

Algebra II
In case you wanted to see the solutions to last night's homework, they are here:

4/7 HW Solutions

**Tonight's homework: please print out the "4/8 HW Sheet" and complete it, and bring in your answers tomorrow. If you cannot print them, then rewrite the problems on a separate sheet of paper and work them out on it.

Random Brain Teaser:

A newly married couple recently bought a cottage in a small mountainous village in Vermont. While they were there, the power went out due to a storm, and there was no sign of an early recovery. So they decided to stay at the husband's parent's house until they received power again. Now, the town where the cottage is was so small that the news of the power outage wouldn't be covered in the news, and they were so new to the neighborhood that they didn't have any contacts in the town or even the phone number of the local police department. How then, from the husband's parent's house could they discover when the power was back on in the cottage? (Hint: This brainteaser predates the internet)

Textbook: pp455-456 #'s 4, 6, 19, 23, 24, 32, 34, 35, 40, 47 

Problems not in textbook:

  Suppose A = sin(x) and B = cos(x), and x is in QI.

      Find the following in terms of A & B:

          ex) sin(2x) = 2sin(x)cos(x) = 2AB

      

          1) sin(x/2)     2) cos(2x)     3) sin(3x)-sin(x)

**If you are stuck or want to check over your work, Mr. Hurley has been nice enough to provide solutions for you here.  (For real this time!)

An exciting day for Scientists...

Sometime today around 9AM EST, Dr. Phillip Rosenguard, head of reanimatory bilogical research at Harvard University became the first successful scientist to reanimate a deceased human being.  Some fear that Mary Shelly's depiction of such an event will come true, and this human brought back to life, whom Rosenguard has named Odan (Once Dead, Alive Now) will destroy his maker as well as regular townsfolk.  Dr. Rosenguard assures others though that Odan is a friendly creation, however.  "[Odan] wouldn't hurt a fly, literally.  He's even careful not to step on ants."

Today we covered double and half angle identities. (Section 5.5)  Don't forget to consider the quadrant of u/2 when solving you equations!

Spring... brake?

Hopefully this halt in Spring weather will end. I know I want to be outside and experience nature once again!

Precalc:
Today we began our adventure into the world of sums and differences in trig functions. Tomorrow, we begin solving and take section 5.4 a little further!

Pot 'o Gold Tuesday

Happy St. Patrick's Day everyone!

Here's a challenge for the day:

Go find a rainbow, and then follow it until you reach the end.  I hear that only on this day each year, a leprechaun hangs out by the northern end waiting for a friend and collecting loose change.  The loose change he turns to gold and throws into his cauldron.  My hat's off to you if you find this mystical creature!

Precalc

Today we covered two lucky charms: general solutions and multiple angle trig equations.

Day 3 notes part 2

Homework:

In your textbook: p432 #11-24 all with gen. sol.'s chicken

Monday... the countdown begins!

Better start buying sunscreen before all of the spring breakers get it off the shelves!  Four days and counting!

Precalc

Today we expanded our love and knowledge of solving trig equations.  We hit calculator expressions, then using identities, and even touched a little on general solutions.  Tomorrow, more 5.3!

Notes:

5.3 Day 2 notes

Homework:

HW #7 --> out #60,65

p431, #5-9 odd (b only); 17-24 all; 32-40 all

Algebra II

Today, we graphed standard form polynomials.  So we factor just like we did in the last unit, and then we use our graphing knowledge that we've learned this unit.  A fusing of units, how clever of those curriculum writers!

Homework:

p13 & p14

Here are a few videos to help with your homework.  It's a couple of the example problems from class today.
