ok...... i really dont see the direct "contradiction and conflict" of:

1) THEORY of GENERAL and SPECIAL RELATIVITY

2) and THEORY OF QUANTUM MECHANICS


???? can you elucidate this distinction? thanks....

Let the function f be defined by f(x)=2x - 1. If 1/2f(squareroot of t)= 4, what is the value of t ?


Ok for that second equation its written as, one half times f of the square root of t equals four.

My school book says the answer is 81/ 4 (81 over 4).

Here are two vectors:
a = (4.0m)i - (3.0m)j and b = (6.0m)i + (8.0m)j

What are (a) the maginitude and (b) the angle (relative to i) of a? What are (c) the magnitude and (d) the angle of b?
What are (e) the magnitude and (f) the angel of a + b; (g) the magnitude and (h) the angle of b - a; and (i) the magnitude and (j) the angle of a - b? (k) What is the angle between the directions of b - a and a - b?

Ok so here is what i did, i wrote it over as sin(1/x)/(1/x) the denominator is the reciprocal of x and if multiplied out will be the same. NOW does this equal one? That is the answer my teacher gave me (that it is one) but im not sure if that is the correct work. I graphed it on my calculator but im not getting a good picture. Is it supposed to be in radians?

What about if you have the same problem but have x^2 in the beginning instead of x? the answer my teacher gave me is infinity, but that would have to be since i do the same thing idid above.
limx^2 (sin1/x) as x approaches infinity.
(x sin(1/x)/(1/x)= x(sin(1/x)/(1/x))= x*1 --> infinity times 1 equals infinity. is this correct? for both problems?
THANKS!!!!! im really stressing out over this!
