Awesome! I haven't received my catalog yet, but I definitely hope people buy them! Lol, it isn't exactly a new arrival, it was listed on their site for maybe 7 or 8 months now.

Thank you! It has been a very exciting venture! I probably shouldn't release my profit margin; you probably understand. They didn't buy the rights from me; but rather they send me a fax requesting "x" number of kits, and then I ship them off. So I am free to sell to other companies and people. I have a few deals that I hope to accomplish this summer.

What do you need help with? With more complex functions, you will not be able to use the basic theorem, but rather substitution.
For example:
Taking the integral of 5((5x+1)^1/2)dx

Here we need to substitute. (5x+1 is under a radical, which is why it is raised to the 1/2.

So first we will be doing something called substituting for "u".
So let "u" = 5x+1 (which is the value under the radical)
du = 5 dx
Now we just plug in. We see a 5 dx in the original function, so that would be du. Since du = 5dx Next, we see a 5x+1 in the function, so we replace that with u. (So now you put the u under the radical)
Your new integral would be, Taking the integral of du*u^1/2 Now take this integral to get 2/3u^3/2 + C. Now the last step is to plug you u value back in. So your final answer would be, 2/3(5x+1)^3/2

It is hard to explain in words, but I hope you get the idea.

I bought an SD card reader at my local office supply store. It is very easy to use because it works just like a flash drive. Plug it in, load the music on to the card, and then remove the micro SD from the reader and stick it into the phone. I have an Env2, so if you have any more questions let me know.

Yea, I changed schools so I had to switch to a new picture.

Yes I do!
