cubexican

Hello, I'm Keith (cuban+mexican=cubexican) and I'm a high school senior with a heavy interest in the sciences and math. I dabble in DJing and I'm going to Purdue University next year to study physics.

Thanks, I appreciate it.

I haven't learned trig substitutions, but I gave it a go and only got so far...I realized that I didn't necessarily have to find out that integral in order to solve the larger problem at hand. Thanks for the help!

No, I would guess that my teacher would expect us to solve the problem by substitution or simplification (possibly by multiplying the function by a "carefully chosen value of 1", if that makes any sense to you).

As part of a larger problem I need to find the definite integral from -4 to 0 of the function sqrt(16-x^2). I know that I'm overlooking something simple here because I've done harder problems without this much difficulty. I've tried to solve it by substitution by letting u= 16-x^2 then du=-2xdx -1/2du=xdx and from there I don't know how to manipulate the function to substitute the -1/2du. I think that simplifying the function is probably the way to go, but I don't see how to go about it. Thanks in advance.

Woops, misread

That's just ridiculous. If you try to calculate the amount of space that the intestines would take up if they were compressed into something (say a human body), it would be larger than the human itself. I've read in textbooks that it's 25 ft combined.

I learned that a theorm is something that must be proven to be believed true and a law is something that must believed true without any proof.

It's all very simple. I also agree with budullewraagh, if you had a specific question it'd be easier for someone to help you. I'm sure that if you read the chapter in your chemistry book that pertains to the homework you'd get it.

It's the same out here in IL. What I'm doing this summer is taking next year's math course this summer at a community college. Since math is a year long course the class is about 4 hours long and about 3 or 4 days per week. I have to take it at a college because my high school only offers semester classes over the summer.

I think it's because you're feeling the tickling and doing the tickling. You have nerve endings on both your fingers and wherever it is you intend to tickle

I just got back from school, I was playing badmitton in the gym. I watched the eclipse outside afterwards.

I am still disturbed by the fact that the child would indeed be dying, but in the case of rape abortion is for the sake of the mother.

When one has sex willingly they are accepting the possibility that she can become impregnated. In the case of rape that person has been traumatized and was violated. That person shouldn't have to go through carrying a child in her body for 9 months and then going through the pain of birth to a child. A child that is the everlasting memory of the night she was violated. In the case of rape and incest I'm pro-choice, otherwise no. In both cases 100 lives were taken, but a person would react more intensely if the egg was more developed and more human-like. That is psychological.

Even in the case of failed birth control I still believe that the impregnated woman should not have an abortion. She made the choice to have sex, protected or unprotected. On all forms of birth control they clearly state that it is not 100% effective.
