y=x^2 x=\sqrt y ?

You multiplied it wrongly...

INTJ 89 38 88 11 Another interesting test: here(I'm RCUEI - Inquisitive)

For #1 the final answer(first derivative) is (e^{4x} \cdot 2x^2) \cdot (4x+3) not 2x + 3...you multiplyed by 2 insted 4... Edit...even more simple it is if you leave it like this 6x^2 e^{4x} + 8x^3 e^{4x} and make a second derivative...

Well you forgot to add change 480 to -480 since you flipped sides. So...5t^2-100t-480=0 now the solutions are -4 and 24 and when you put them in the equation you get the correct solution. \frac { 20 \pm \sqrt { (-20)^2-4 \cdot 1 \cdot (-96) } } {2 \cdot 1} \frac { 20 \pm 28 } {2}

Or you can use OpenOffice write the Equations in it(word-like style) and then save it to pdf. Completely free and simple.

P = I \cdot U would be ok.

Thank you all for the info.

Hello, I can't find :confused: where do we get the starting neutron(s) for the chain reaction in the reactor. I'm aware that then the splitted atom emits enough(in fact even too much?) neutrons to selfsustain the reaction, which are then slowed down to be able to split uranium and so on...

Well this E stands for \cdot 10^{2nd nr.}, for example, 2E5 is the same as 2 \cdot 10^5. So it is for multiply the first number with 10 to the power of the second number(after the E).

Well if you want to calculate for instance 2^5 you should use the x^y function not the Exp function, the Exp function calculates 2 \cdot 10^5. I hope that I understood what you meant.

Well, if the Earth rotation slows down for about 1.5 milliseconds(1.5x10^-3 sec; per day) in one century it would take 100.000 years(1000 centuries) until the day would be 1.5 seconds longer.

Hm i now read that your pc is socket1(this is for 486 processors), why would you run xp on a 486(isn't it kinda slow, really slow :D )? Or it is a slot 1, which are pentuims 2,3 and celerons(which i have for server, and the bios, has a boot order utility).

Well usualy it it in Advanced BIOS features. Are you sure that the jumpers are in the right place(when the pc starts it should show the ide devices connected(after the ram testing),http://www.pcbuyerbeware.co.uk/StartupScreen.gif" , if there are both of the discs, than they are connected ok and...

Right now, on my comupter, I have: http://www.mathcad.com/" . For most things that I do, Mathcad is good enough.
