Where do you derive this from, other than your imagination? Where in the gospels does JC put aside his Jewish faith? You are confuting the gospel Jesus with Paul. Jesus reinforced Mosaic Law, Paul despised with it. Circumcise does not make a Jew Jewish....paraphrasing. OMG!! Now ot is about...

Like most Christians you ignore the question. For 2000 years what have been the consequences of this movement? Jews, Muslims and Christians ostensibly have the same god. Yet there is conflict between the three faiths and conflict within each faith. Jews, Christians, and Muslims emancipation...

And for 2000 years what has been the overall results of that movement? Be specific if you can, no generalities.

A good basic technical calculus book. https://students.aiu.edu/submissions/profiles/resources/onlineBook/x2Y3u2_basic%20technical%20mathematics.pdf

Watched an old movie about Custer with Errol Flynn as Custer. Given what we know historically of Custer the movie was essentially horse shit. It paints Custer as compassionate and sympathetic to the 'Injuns' instead of the genocidal man on a mission he was. I visited the battlefield on a cross...

Beyond straightforward textbook kinds of problems I always used numeral integration. and differentiation. n = 1000 y = np.ndarray(shape=(n),dtype=np.double) derv = np.ndarray(shape=(n),dtype=np.double) integ = np.ndarray(shape=,dtype=np.double) t = np.linspace(0,2*np.pi,b) dt = t[1]-t[0] for...

And the transform of step function is sin(x)/x n = 1000 y = np.ndarray(shape=(n),dtype = np.double) t = np.linspace(0,20*np.pi,n) #radians for i in range(n):y[i] = np.sin(t[i])/t[i] y = abs(y) plotxy(0,max(t),-1,1,t,y,"","","")

I would never discourage anyone's interest in math, The math and science forums once lively have been dead for a while. Post away.

Jaryn I know next to nothing on number theory but I know something about step functions and transforms. Se the post on the FFT thread, you can see the transform for yourself.

Responding to Jaryn's question on transform of a step function. The true unit step is theoretical, nothing changes in zero time. It is important in electronics. A fast rise time digital signal generates radiated electromagnetic noise, and the frequency spectrum of the noise is the transform of...

I do not know, but it is .related to the normal distribution. An overview http://www.mhtlab.uwaterloo.ca/courses/me755/web_chap2.pdf One use for the inverse function is generating a normal distribution given a mean and standard deviation. Pass a mean u and standard deviation sigma a, sort...

Haven't watched SNL since the 80s. Who or what is Che?

1st column x, 2nd erf(x), 3rd ierf(erf(x)), 1st and 2bd columns should be the same ideally without numerical issues. +0.123456789012345 0.138601545069331 +0.123456789012336 +0.223456789012345 0.248009349056034 +0.223456789012325 +0.323456789012345 0.352643009080857...

The error function and inverse error function. Both important. The error function is done by numerical integration. The inverse function by a series. At small x values the precision is about 12 decimal places. It goes down as the magnitude of x increases. The c coefficients for the inverse...

It is easy. Go to Mar a Lago and on national TV kneel down and kiss Trump's ass. It is what house speaker Johnson just did.
