Undergrad Is x^pi Real for Negative Values of x?
The plot of x^(pi) looks like an odd function, does that make pi an odd number? http://www.wolframalpha.com/input/?i=x^pi same goes for x^e http://www.wolframalpha.com/input/?i=x^e- cstvlr

Undergrad Is the statement 'int x^n from 0 to 1 = 1/(n + 1)' true?
int x^n from 0 to 1 = 1/(n + 1) But as n approaches infinity the answer becomes zero. -

Why do I get two solutions by integrating sin(x)cos(x)?
By setting u = sin(x), I got 1/2 (sin(x))^2 By setting u = cos(x), I got -1/2 (cos(x))^2 The two answers are not the same, why are there two solutions?- cstvlr

Graduate Is there a proof of parallel universes?
Every science documentary I've watched talks about parallel universes. Is it a hypothesis formed by mathematical models, if so what are they?- cstvlr

Graduate We can not get back to our original position?
I was thinking about how the Earth moving all around the Sun, and the Sun moving around the galactic center of the Milky Way and having read that galaxies are moving away from one another at the speed of light, and If string theory is correct, the Universe is moving in a different vacuum, so it...- cstvlr

Comp Sci Plotting sin x on an XY Plane with C++
Homework Statement Hi, I'm writing a c++ code which is about making an xy plane with dots and then using an array an plot a math function with a character. the functions i need to plot are sin x, sqrt x and a polynomial. so far I attempted to make a function for plotting sin x, but I always get...- cstvlr

Converting square root to perfect square
no its in an equation form, C(x) = [(9-x) + 1.25sqrt( x^2 + 36 )], where C(x) is a function. and they're trying to solve for x, so they used the method above, and I know how to solve it, but I lost it when they used let x = 3( t - 1/t )- cstvlr

Converting square root to perfect square
Homework Statement Hi, I have a problem in my book in which they use a method of making sqrt( 36 + x^2 ) a perfect square by simply making x = 3( t - 1/t ) and then we get 9( t + 1/t )^2 by substituting back into sqrt(36 + x^2). My question is that why did the chose 3( t - 1/t ), is...- cstvlr
