This time dealing with sine.

Would anyone like to share what we learned?

### What's W?

How did we find the exact time for W?

We talked about using guess and check. That method will work. You will eventually get the final answer. However, it will take a while.

Are there other more efficient ways to find W?

Please share your thoughts....

### Moving Carts, Turning Ferris Wheel

Today we talked about HW14. If W=25 seconds, what will the x-coordinate of the diver be? Where should the cart start out so that the diver will fall into the tub of water on the cart?

Using the HW14, we again attempted to find the value of W for our Unit Problem. What did people do to try to find W? Did you find a range of possible answers for W? Did you find a value for W?

### HW14: Cart Before the Ferris Wheel

In this assignment, the diver is released exactly 25 seconds after the Ferris wheel began turning from its 3 o'clock position.

1. What is his x-coordinate as he falls?

2. Where should the cart start out so that the diver will fall into the tub of water on the cart?

Suggestions? Questions? Hints?

### HW 13: Planning for Formulas

Does anyone know the formula for.....

- The diver's height at the moment he is released?
- The diver's x-coordinate at the moment he is released?
- The amount of time the diver is falling?
- The cart's x-coordinate when the diver reachers the water level?

### HW12 Where's the Cart

In class today, we discussed HW12. The book said the cart begins 240 feet to the left of the base of the Ferris wheel and moves to the right at a speed of 15 ft/sec.

Where is the cart after 14 seconds?

Where is the cart after 23 seconds?

What formula did we develop in class that tells us the x-coordinate of the cart in terms of time?

### First Quadrant Platform

In class today, the equation to find the horizontal position for the first quadrant was brought up.

- x(t) = 50 cos (9t)

How does this equation work?

Does it work for every value of t? Or does it only work for first quadrant values?

### Quiz 3

How did the quizzes go?

Any tips or pointers to help your classmates avoid making mistakes on our next quiz this Friday?

I have one. Make sure your calculator is in Degree Mode and not in Radian Mode.

### POW2: Paving Patterns

What have people tried?

The POW recommends starting with shorter paths...and looking for patterns.

What tools could help us see patterns?

### Welcome to Jones IMP4

Good morning....on this day we become legendary....

I would like to use this blog as a way to discuss issues and problems from class.

I hope that through this blog we can exchange ideas, comments, and questions.

I will use this blog as an additional tool to assess your class participation.
