i like this one a lot: phillips - introduction to quantum mechanics it s a beginners book but that's what i am and i like it :)

i think i actually managed it :D did the trig thingy and then used Conjugate (that one was silly obvious /blush) and i got a result thank you :)

hmm yeah i wish they were linear well only problem i really got is that i don't know how to conjugate Exp[ i x] or to make shown as Cosx + i Sinx P.S equations were: a1 - a2 + b1 - b2 -(20/197) Sqrt[2555] (a2 - b2) Sqrt[-1 + x] + 20/197 Sqrt[2555] (a1 - b1) Sqrt[x] -a3 exp[20/197...

so i was kind of wondering if anyone knows of any mathematica tuorials for how to operate with complex numbers (i know how to do it by hand but solving a set of 5 equations all complex just seems suicidal :D ) so any help d be appreciated

cool :) thanks

tried it and it works :D thank you (does it work for x^n+... aswell?)

hmm sadly its not a full square :( solved it with taylor series (got and estimate and its better then nothing)

[SOLVED] how to solve and equation? Homework Statement sqrt(ax^2 +bx) - sqrt(cx^2 + dx) = e where you know a,b,c,d and e Homework Equations i don't know The Attempt at a Solution i put the entire equation on the power of 2 and then simplified adn then repeated again ... and i got...

time doesn't slow down actually ... it stays the same its just that its just that time isn't an aboslute parameter at high speeds : per say you would make yourselft a new parameter that is absolute then that parameter would show different times in the system taht travels near c (or is near a...

aye ... well i just wondered of alternative methods :D

Homework Statement one is powering a photonic rocket with photons. what is the speed it reaches when its mass is half its starting mass. and per say you would start stoping then ... how would that look like (equations and sentences) Homework Equations invariance of the 4D vector of...

try drawin a picture : then set some coordinates and then use trigonometric functions to see what's the speed in the axis that's in the right angle towards your wall (sounds confusing?) and then just apply it to the equation you have
