mostly middle schoolers, and not necessarlity for physics, but it definitely can be. i was thinking about doing a lesson on statistics, but there is so much out there with it, i just do not know.

I'm in need of making a lesson plan that utilizes technology. I can't find any good ideas. Checked out TI and NCTM's websites, to no avail. Anyone have any cool ideas or websites that would work? The lesson plan needs to use technology by means of Excel or a TI calculator.

Ahhhh, I knew it was something with algebra. Thank you very much. I understand that now. because something multiplied by a must mean that a is divisible by b. Thanks much! If only I can get this second one. :mad:

Two questions here. I know the definitions, but cannot formulate a through proof. 1.a and b are positive integers. If a^3 | (is divisible by) b^2, then a | (is divisible by) b. Now, by definition, I know that a^3*k=b^2, for some k. Also, I know that a * j = b for some j. But where do...

I've worked all four years. Loved it too. Felt that I did much better in classes. I am the type of person who always has to have his hands into something, call me crazy. What you need to do is to get one job and see how it effects you. If your grades and such drop, drop the job.

Y=30x+26 It is just simple algebra I believe.

Do you honestly think I have not tried that. Give me some credit. :devil:

well, this is a summation problem. it is the summation of 1/n(n+1) equals "what." the "what" is what I'm supposed to find. the 1/n(n+1) is already given for the one side of the equation, i need to find what the summation is also equal to.

Is there anyone who can help me? I need to find a pattern in these numbers: 1/2, 1/6, 1/12, 1/20, 1/30, 1/42, 1/56. Now, I know just by looking at the denominators, if I could only work with those, I could use the formula: 2n+a_n_1. But I have that fraction, so it's all screwy. Anyone see...

Ok, so on the outside of the product, I would have k^k=product a_i? I have another question that just blows my mind: The product is the same, but it reads ia_i. There is no k in the question, how am I to write this in terms of k??

I have a quick question. In my book, there is a question that says to express each of the following products in terms of \prod_{n=1}^\k\a{i}, where k is constant. Now, my question is this: \prod_{n=1}^\k\ka_i. Would i just pull the k out because it is only a constant and move that to in...

I do not know where you are driving, but if you are in a line of traffic, turn the truck off. Sitting idle will waste more gas than turning the truck off and firing it back up. If you have A/C, it is actually better to drive with the windows up on those long drives. The "wind tunnel" that the...

I feel that "only the strong survive" applies in this gas mess. If you can afford gas, you will buy it, no matter how much it is per gallon. If you cannot afford, don't buy it. The people who have the SUV will ultimately buy the gas because of these two reasons (in my eyes): 1. They need the...

My precalc also introduced product and chain rules. All of your items you have listed seems to be just like my precalc class. (long time ago.)

Hey, I'm just letting you know. Sue me.
