### Thrusday March 14, 2013

Happy Pie day!!!

Today in class talked about identites and the difference between simpifying and proving.

Simplifying: Start with one expressiona dn use identites and algebra to turn that expression into an equivalent expression.

Proving: Start with two expression and use identites and alegbra on one or both expression until both sides are the same.

Homework is #13 on the homework sheet. And tommorrow bring your blue book to class!

### Wednesday March 13, 2013

Today in class we reviewed #11 and #12 from the homework sheet. There is no homework tonight!

### Tuesday March 12, 2013

Today we took a quick quiz on reciprocal trig functions. We also took notes and prove the statement that sin theta squared + cos theta squared = 1

## Tuesday, March 5, 2013

The homework for tonight is to study for tomorrow's quiz.

For the quiz, you need to know:

- How to graph a tangent function (5 points)
- Graph the 3 inverse trig functions (5 points) and answer domain and range questions about them, why they make sense, and what the axes represent.
- You will need to know how to solve linear trig equations
- Primary solution and what it means
- All solutions on given interval
- Find an expression for all solutions
- Be able to deal with happy and unhappy numbers
- Be able to use the graphs to find these values
- Solve Tangent equations

## Monday, March 4, 2013

**In Class:**We went over examples of solving cosine and sine inverse functions. We learned that the primary solution is the number given by the calculator because it is the solution on the inverse

*function*. Then we looked at all solutions on [0, 2pi]. We learned it was helpful to draw the graph and then locate the solutions on there. Finally, we learned how to find all solutions (adding the period*n to the primary and secondary solutions). During class we talked about course selections as well.

**Homework:**Thursday: gold packet p.583 #12, p.585 #3. And the writing assignment was due on Friday.

Friday: Finish the first three problems of the practice problems packet we were given.

## Tuesday, February 26, 2013

**In Class:**Today we took our quick quiz at the beginning of the class. Then, we all received an equation and had to find our partner. Once we had partners, we looked at all the equations and grouped them by their similarities. When the bell rang, we were solving our given equation.

**Homework:**Work on the writing assignment due on FRIDAY!

## Monday, February 25, 2013

**Essential Question:**How do we graph the inverse trig. functions?

**In Class:**Today we went over how to graph the inverse of sine, cosine, and tangent. One method that we focused on was making a table using the coordinate points on the parent function and switching the values to find the inverse. We also talked about the importance of concavity. At the end of class, we were asked to solve the problem: 2 cos(x) -1=0. Mrs. Prior left us to think about how many solutions that equation would have.

**Homework:**page 288 #1-14 and #29-40. Tomorrow we have a quick quiz on graphing trig. functions!

In Class: Today in class we went over last nights homework, went over some essential questions and what will be on the big quiz. We went over more problems with logs and natural logs. We also took a mad minute.

Homework: Page 450, Numbers 6 and 7, page 452 number 5 and page 453 number 4! Study for quiz on Thursday!

### Monday (02/04/13)

In-Class: Today, we worked on our partner worksheets, finalized our answers, and handed in the worksheet to be graded. After, we took notes on how to draw graphs involving the special number "e" (exponential and logarithmic). These graphs also included multiple transformations.

HW: Blue Book (4B), Pages 452-3: #1 and #2. Also, we have a test on Thursday on inverses and logarithms!

### Friday, February 1, 2013

In class: Today we reviewed Wednesday's homework, learning that e is a concept and not a number, which explains the structure of the formula for compounding continuously. We also began a partner worksheet that will be collected Monday.

HW: Finish the partner worksheet.

HW: Finish the partner worksheet.

__In class:__Today we went over certain parts of last night's homework on the board and solidified our understanding of how to rewrite exponential functions with different bases. We also learned about natural log and the significance of e as a number and as a base in an exponential function. When e to the power of x is graphed, it has the slope of 1 at the point where it meets the line y=x.

__Homework:__A worksheet with more compounding interest and exponential function practice.

__Essential Questions__: How do we express exponential function in equivalent forms with different bases? How do we use exponential functions to solve problems about compounding interest?

__Reminders:__There will be a test on this material sometime next week!

## Tuesday, January 29, 2013

**In class:**On Monday and today we took notes about bases,compounding and continuous compounding. We learnt about e means and limit notation.

**Homework:**Pg.451 #2 and Pg.452 #3 (Both of these are modeling problems and remember to do this because it will effect whether are not you can complete a rework for a test or quiz)! Just in case you didn't do Monday's homework it was a compounding worksheet.

### Friday, January 4, 2013

__In Class__: Today we did a mad minute at the beginning of class. We also learned how to solve three different types of log functions. The first just uses the definition of a log, the second uses the properties of logs and the definition, and the third has logs on both sides.

__HW__: Do GPC#12 and work on the midterm-review packet.

## Thursday, January 3, 2013

__In Class:__We had a Mad Minutes quiz at the beginning of class, then we went over the answers together. Afterward, we fixed a misprint in our midterm packet on #21: the function should be f(x)=log(base 3)(3x-6)+2 instead of 10^(x+1)=29. We got the rest of class to work on the Partner Writing Assignment, which is due next Thursday, January 10. (We got to choose our partners.) Each pair should turn in one final draft, and Mrs. Prior would like it if we sent them to her email so she can grade them on her iPad.

__Homework:__Do GPC #11, work on the midterm packet as well as on the Partner Writing Assignment, and don't forget that the individual Online Writing Assignment is due tonight by 11:59 pm!

__Reminders:__There is a big logs quiz next Friday, January 11! Our midterm exam is the Friday after that, January 18.

__Essential Questions:__

- What is the definition of a logarithm?
- How do we rewrite exponential equations?
- What are the properties of logs and how do we use them (Exponent, Product, and Quotient)?
- How do we change the base of log equations?
- How do we graph basic (ex. log base 2 of x) and transformed (ex. log base 2 of (x+3)) log functions?
- How do we solve exponential equations using logs?
- How do we solve log equations?
