Oh man I feel like an idiot! Thankyou all!

Speak to me/Breath is the best though.

So I was messing around with some basic u-sub calculus and came across this problem. Any help would be greatly appreciated! Homework Statement \int \frac{3x^{2}}{x^{2}-7} dx Homework Equations I'm using u-substitution, as stated at the beginning. The Attempt at a Solution I see...

It's perfect! Thanks!

I meant a 3d graphing calculator. I need one to work with double integrals in Calculus 2.

Very cool you taught yourself all that, is there a particular question in this thread that you would like answered? Also, I taught myself all of that by age 15, it's cool to see someone with similar ambitions.

Does anyone know of a good online 3d calculator that will actually work. Thanks.

Thank you all! Very interesting.

"Physicists use fields to describe the things that don't just have a particular position, but exist at every point in space. For example, you can think about the temperature in a room as a field- it may be different near an open window than near a hot stove, and you could imagine measuring the...

Will someone please explain to me how a theory, such as a quantum field theory, be expressed in more than three dimensions? Is this referring to the spatial dimensions we live in now, or what? And how does someone even begin to ponder these multiple dimensions?

Will someone help me to understand sinh, cosh, and tanh. I know they have some relevance to hyperbolas and trigonometric identities. Thank you.

You are given a table and (maybe) a picture of a graph. Here are the points given: 0,0; 1,-.7568; 2,.99061; and 3,-.988. What is the function? Is it possible to figure out by hand?

What age would you guys think?

The parabola's base or curve is at the origin, the lines point up left and right. I'm focusing on the parabola's part that is to the right of the y axis. So half of a curve rotated around the origin looks like a curvy cone. Thanks for you guys' help, I now have the answers. Thanks!

No that's not correct sorry
