1. ### Integral: square root of tan x

My class, teacher included, cannot seem to figure out the integral of the square root of tan x. Maybe someone here can help? thanks, jeremy
2. ### Schools Retaking Classes at the college level

i have talked to at least two people who have said they they have/will retake all the AP/college courses they took in high school at whatever university they are going to. one friend plans on retaking calculus (from 1) because, supposedly, it will be under better teachers. he also says...
3. ### Estimated area under a curve program

for simplicities sake i used -> as an arrow. i see now that it looks like a minus greater than sign.
4. ### Estimated area under a curve program

I wrote a TI-86 program for estimating the area under a curve using "Right Rectangular Approximation Method" (RRAM), "Left..." (LRAM), and "Trapezoid" method. However, it refuses to work. Sometimes it works, but I have gotten answers that are way off. Once i got something that was 3x the...
5. ### What do you think of this?

read this little bit http://www.whatthebleep.com/crystals/ the scientists involved in this project seem to think that thoughts can have an effect on the quantum level, leading to different formations of ice. i find it strange that the happy ideas we think of (love and gratitude, mozart)...
6. ### Curvature of light and its effect on reality

Unfortunately, I don't have the article. However, thank you for helping with what you could. I thought the argument seemed a bit illogical.
7. ### Curvature of light and its effect on reality

Today my teacher mentioned a past article in scientific american that dealt with the modification of reality due to relativity. According to her (and i am not sure this is true) light can be perceived in different places according to the position of different people. For instance, if i am...
8. ### Derivative of Piece-Wise Function

sounds good thanks a bunch
9. ### Derivative of Piece-Wise Function

I am doing my calculus homework and two problems are holding me up. The first says: Using one-sided derivatives, show that the function f(x) = x^3, x_<_1 3x, x>1 does not have a derivative at x=1 Now it is painfully obvious that the function is not continuous at x=1. however, i...
10. ### Engineers and engineering students: what did you get on ACT

It is out of 36 now...might have been the same then. so you did well in high school and were shocked a bit at first in college? what type of engineering did you pursue? i have heard that you go to class, study, and do homework for about the same amount of time you would spend working at a...
11. ### Engineers and engineering students: what did you get on ACT

Engineers and engineering students: what did you get on the ACT? from what i understand, the ACT is an approximation of how well you will do in your first semester of college. i know a bunch of people will say, "it doesn't matter what i got...i just worked hard my first year of college."...
12. ### Is chemistry useless?

why do you say physics is in crisis and then not explain what you mean? physics appears to be doing fine from my perspective. classical, relative, and quantum physics are all being applied with accurate results. the only "crisis" i know of is the unification of general relativity and...
13. ### H.S. Senior Year Blues (HELP)

As an undergraduate, if you get your degree in some kind of engineering, can you go on to graduate school for a physics degree? while i plan on doing engineering, my second choice is definitely physics. just looking for options in case i find an engineering job to be boring and i want to...
14. ### Philosophy in The Elegant Universe

I have actually taken social studies/history all four years. this year, however, i took government for four hours a day over the summer so i could make room for AP chem II. little did i know, french 4 was the same hour as AP physics II, and we see which won that battle. Next semester Lit and...
15. ### Overdrive on a Truck

alright so i should basically always keep the truck in overdrive except: when climbing a long steep hill and it is switching gears erraticly when i am towing/have bed full of rocks and am climbing a rather steep hill thanks for all the help guys. my truck and i thank you.
16. ### Overdrive on a Truck

so how should i be using overdrive? do i need it on my daily 10 minute commute to school, or only when i get going on a highway for half an hour? should i be shifting from D to OD while i am driving (i understand shifting between certain gears while pressing the gas can damage the...
17. ### Philosophy in The Elegant Universe

one of the reasons i was kind of excited about getting to use the book for an independent novel is because it isn't really a novel...exactly as you put it, selfAdjoint. i wonder how the book can be a national bestseller though when a very small percentage of the world cares about science, an...
18. ### Philosophy in The Elegant Universe

I have convinced my english teacher to let me use The Elegant Universe as an independant reading novel for my Literature and Philosophy class. (As a sidenote, this is really exciting to me because now my entire day (except for band) is science/math: AP Chem, teacher's assistant during AP Chem...
19. ### Overdrive on a Truck

I may be lazy looker but this seemed like the best forum for this question. i just hope there are car people here. i have a 1993 GMC sierra V6 truck (dark blue, in case you were wondering). On the "shifter" i have the option to drive in "drive" or "overdrive." Now i don't really...
20. ### Whose frame is right ?

i guess i even misunderstood some of my questions... when i said "what will happen with regards to everyone's time," i meant that, if B asked A what time he had (on the phone), would the delay cause A and B's clocks to be the same or would they be different. thanks for all your input
21. ### Whose frame is right ?

so let's say A is moving left at .25c and B is moving right at .75c, but neither know it. Both are obviously experiencing time dilation, and to an invisible stationary observer at the meeting point, B is aging slower than A. But let's say some physically freaky event occurs, such as both...
22. ### Whose frame is right ?

whose frame is "right"? i have been reading The Elegant Universe and i have learned quite a bit. however, i don't understand how person A can say that they are still while B is the one who is moving and vice versa. I guess i understand how each person can say they are "still," but i don't...
23. ### Can you help guide me?

moneys not THAT big of a deal. my dad just told me we can probably afford to pay for U of I. really, the only schools in my area are junior/small colleges. i looking for the best. i was more worried about how good the school is/what the school is like etc.
24. ### Can you help guide me?

greetings i am a high school junior that lives in southern illinois. i go to a public school. i haven't taken the SAT or ACT, but i have taken the PSAT/national merit scholarship and gotten a 209. I probably will be one of the valedictorians in my class. last year i took AP world...
